1. Choosing the Right UCDP External Support Dataset

The Uppsala Conflict Data Program External Support Project, as of version 1.0-2011, produces two
separate datasets, the UCDP External Support – Primary Warring Party Dataset, and the UCDP External
Support – Disaggregated/Supporter Dataset. The two datasets are analogous, i.e. contain identical data
structured in a different manner to simplify various types of research such as different types ofstatistical analyses.
For a graphical illustration of the differences between the two UCDP External Support Datasets, seeFig. 1.
Both datasets are fully compatible with the most recent versions of the UCDP datasets, such as the
UCDP/Prio dataset, the UCDP Dyadic Dataset, the UCDP Actor Dataset etc., as well as with the UCDP
database as current at the date of production of this database.
The External Support – Primary Warring Party Dataset uses, as an object of analyses, the ‘primary
yearly warring party’, i.e., each side active (involved in fighting) in each conflict dyad for each year when
the conflict was active.
Each row in the dataset contains one such side – i.e. one receiver of external support. Within thisdocument, for consistency with the UCDP database and other UCDP datasets the receiver of suchexternal support is also referred to as a primary warring party – see definitions below).
In this dataset, external supporters that gave support are aggregated - all supporters giving support to aside engaged in a conflict dyad in one year are listed, as a list in a single cell. Types of external support
identified are also aggregated to the level of the receiver of support, i.e. if 3 supporters provided various
types of support to a given receiver in a given dyad-year, but only one supplied weapons, this type of
support is registered in the dataset for the given receiver and dyad-year, as types are aggregated fromthe point of view of the receiver of support.

UCDP External Support Project // Primary Warring Party Dataset Codebook, v. 1.0-2011

Further, this dataset also contains comments by the original coders on the type and size of support.
Thus, this dataset is best suited for analysis from the perspective of the receiver of support, as long as
the analysis does not require the exclusion or inclusion of supporters, or the distinction of who supplied
what. As it is more compact than the External Support – Disaggregated/Supporter dataset, it may be
more suited for manual consultation.
The External Support – Disaggregated/Supporter Level Dataset uses, as an object of analysis, theexternal supporter for each individual side supported, in each dyad-year when a conflict was active(each incident of support). The basic difference from the UCDP External Support – Primary Warring Party
Dataset is that, if more than one supporter gave support to a party in a year, each individual supporter islisted on a separate row. As such, types of support need not be aggregated, each row containing thetypes of support that each external supporter gave to a certain receiver in a given year.
Ex. In the Government of Uganda – UNLF dyad, three supporters provided support to the Government of Uganda
in 1979 – Libya, the Soviet Union and The Islamic Development Bank. In the aggregated dataset (External Support –Primary Warring Party Dataset), this event is described in one row, and the variables dealing with type of support
list overall support received by the Government of Uganda in 1979.
In the External Support – Disaggregated/Supporter Level Dataset the same information is described in three
separate rows, one for each of the three supporters, individually assessing the type of support each supporter
provided.

Thus, this dataset is best suited for analysis from the perspective of the supporter, (ex. analyses on
number of supporters in a given year, actions of a particular supporter in a given region, etc.) or for
more complex analyses (excluding some supporters, excluding some types of offered support etc.).
UCDP provides both datasets and codebooks free of charge on its web page (http://ucdp.uu.se/).

1. Introduction

This document describes the UCDP External Support Dataset – Primary Warring Party Dataset, aproject within the Uppsala Conflict Data Program (UCDP) at the Department of Peace and ConflictResearch, Uppsala University.

UCDP External Support Project // Primary Warring Party Dataset Codebook, v. 1.0-2011

The unit of analysis in this dataset is a yearly primary warring party / receiver of support (that is, an actor
involved in an interstate or intrastate armed conflict, more specifically one of the parties who formed
the incompatibility) and it lists all the actors supplying said party with support in any given year.
Furthermore, the support received is divided into different categories. The UCDP External Support
dataset is an integral part of the UCDP database, and thus contains all warring parties – both state – andnon-state ones – included in the UCDP database. It is also compatible with the post- 1975 data in the
UCDP dyadic dataset and the UCDP/PRIO armed conflict dataset and can be used together with the
UCDP Actor Dataset.
Version 1-2011 of the UCDP External Support Dataset corresponds to the UCDP Database Categorical
Variables 1975-2009, UCDP/PRIO Armed Conflict Dataset v. 4-2010; and the UCDP Dyadic Dataset v. 12010.

2. Definition of key concepts

3.1_External support
The phenomenon that this dataset attempts to capture is external support to the primary parties to aconflict (see below for definition of “primary party/receiver of external support”). UCDP differentiates
between two categories of external support, both of which are included in the UCDP External Support
Dataset; secondary warring support and secondary non-warring support. While the former is included as
one type of external support in the dataset, the latter is divided into ten types of support.

3.1.1 Secondary warring support
Secondary warring support is defined as support to a primary party (receiver of support) that consists ofsending troops to assist in an ongoing conflict. The party sending troops is always a state who shares the
position in the incompatibility with one of the primary parties.
A secondary warring party does not need to meet the 25 battle-related deaths criteria to be included in
UCDP data (see definition of armed conflict below). An active troop participation of their forces isenough.

3.1.2 Secondary non-warring support
Secondary non-warring support is defined as support to a primary party (receiver of support) that isgiven to assist it in an ongoing conflict. The non-warring support can take a variety of forms, including
5

UCDP External Support Project // Primary Warring Party Dataset Codebook, v. 1.0-2011

the provision of sanctuary, financial assistance, logistics and military support short of troops. The party
providing the support should be a state or an organization (in the widest sense of the term) and not an
individual.
It should be noted that anything relating to normal interaction between states (such as profits fromtrade) is not considered to be secondary non-warring support even if the consequences of thatinteraction may be to the benefit of the warring party that is on the receiving end. This is due to theabove-mentioned fact that we only consider support that is actively given to strengthen the party in theparticular conflict and not support which unintentionally happens to strengthen the warring party.

3.2 External Supporter
The external supporter is a party providing external support. The external supporter needs not beotherwise involved in any armed conflict, and thus needs not be included in the current version of the
UCDP Actor Dataset.
As such, the external supporter can be a state government, a diaspora, a non-state rebel group, anorganization such as an NGO or IGO, a political party, a company or a lobby group, or even an individual.
This dataset employs, for actors that fall under the scope of the UCDP Actor Dataset, the same names
and actor codes as specified there, with some exceptions (i.e. the Government of particle is removed forstate actors, some shorter names are in use).
For actors that fall outside the scope of the UCDP Actor Dataset (actors that have never been primary or
secondary warring parties in any conflict, or that have never engaged in non-state or one-sided
violence), an appendix is provided with this dataset. The appendix contains standardized names,
abbreviations and actor codes for such actors.

3.3_Alleged support
Alleged support is defined as claims of external support that are unsubstantiated but have significant
impact on the overall conflict (i.e., on its outcome, on the way the conflict is carried out, on the ability ofa primary warring party to obtain real external support, etc.).
Such allegations of support almost always originate with either another supporter, are present in
influential media and reporting, or are widespread in multiple sources, yet unconfirmed/nonconfirmable. Allegations of support that have limited spread or that are clearly outrageous are notincluded in the dataset.

3.4 Primary warring parties (receivers of support)
The primary parties to a conflict (often referred to as primary warring parties or simply warring parties)
are those that form an incompatibility by stating incompatible positions.

3.5 Secondary warring parties (supporters/senders of support)
Secondary parties are those that support one of the primary warring parties, either by providing troops(secondary warring support) or by supplying some other form of support short of troops (secondary nonwarring support).
For instance, in the conflict fought over governmental power in Angola, the parties that formed theincompatibility were the Government of Angola and the rebel groups UNITA and FNLA. They are thus
viewed as the primary warring parties. During the course of the conflict no less than four states sent
troops to fight alongside one of the warring parties; Cuba and Namibia aiding the government and South
Africa and Zaire supporting the rebels (UNITA receiving assistance from the former and FNLA from thelatter). Cuba, Namibia, South Africa and Zaire are thus viewed as secondary warring parties to theconflict. Furthermore, a large number of states and organizations provided other types of support to theprimary parties. For instance, Israel supplied the government with weapons, while Morocco provided
military training to UNITA. Subsequently, also Israel and Morocco are viewed as secondary parties,
providing secondary non-warring support.

3.6. Armed conflict
An armed conflict is defined as a contested incompatibility that concerns government and/or territory
where the use of armed force between two parties, of which at least one is the government of a state,
results in at least 25 battle-related deaths in a calendar year.
For a more in-depth discussion on the separate elements of this definition, see the codebook to the
UCDP Dyadic Dataset and the UCDP/PRIO Armed Conflict Dataset.

3.7 State actor
A state actor is always the government of a state.
A state is defined as an internationally recognized sovereign government controlling a specific territory,or an internationally unrecognized government controlling a specified territory whose sovereignty is not
disputed by another internationally recognized sovereign government previously controlling the same

7

UCDP External Support Project // Primary Warring Party Dataset Codebook, v. 1.0-2011

territory. See Section 4 in the UCDP/PRIO Armed Conflict Codebook for details on the sample ofcountries covered by this definition.
When in doubt as to who is actually controlling the government of a state, the party controlling thecapital of the state is regarded as the government.
In order to define the total population of states we use the Gleditsch & Ward (1999) systems
membership definition, which is based on the Correlates of War project. Gleditsch & Ward include
countries with a population of more than 250,000 that have ‘a relatively autonomous administration
over some territory’, and is ‘considered a distinct entity by local actors or the state it is dependent on’(Gleditsch & Ward, 1999: 398).
For a discussion on differences between the UCDP definition of a state and that of Gleditsch and Wars,
see the codebook for the UCDP/PRIO Armed Conflict Dataset.

2.8 Type of support
2.9 Literal
UCDP distinguishes between ten different types of external support, based on the kind of supplies thatare provided by the external supporter to the receiver of support.
The following types are distinguished by UCDP, identified by a name, and a literal (a single-letter code
defining the type of support): Troops as secondary warring party (literal X), Access to Territory (literalL), Access to military or intelligence infrastructure (literal Y), Weapons (literal W), Materiel/Logistics(literal M), Training/Expertise (literal T), Funding/Economic Support (literal $), Intelligence material(literal I), Other forms of support (literal O), Unknown support (literal U).
Each type of support is assigned its own, unique dummy variable, identifiable by the literal (ex., one
would look for external_type_W if wanting to look for support falling under the category of Weapons).
For a detailed definition of each type of support, see sections 5.15. Types of Support and 4. Descriptionof Variables.

3. Variables in the dataset

Variable

Brief description

ywp_idnumeric (4-digit positive integer). An identifier for each individual primary
warring party active in a given year in a given conflict. ywp_id is year-specific,
i.e., it is different for the same primary warring party in different years.

ywp_yearnumeric (4-digit positive integer). Year of observation. The current dataset
covers the 1975-2009 periods, containing all years in which warring parties
have been active in the UCDP datasets.

ywp_name

string. Name of the actor (primary warring party/receiver of support), as listed
in the UCDP Actor dataset.

actorID

numeric (4-digit positive integer). The unique identifier of the individual actor(primary warring party/receiver of support), as listed in the UCDP Actor dataset
version 2.1-2010.

bc_id

numeric (3-digit positive integer). One of two unique identifiers of the armed
conflict in which the primary warring party is involved during the dyad-year.
bc_id corresponds to the conflict IDs assigned by the UCDP database.

conflictID

numeric (3-digit positive integer). One of two unique identifiers of the armed
conflict in which the primary warring party is involved during the dyad-year.
conflictID corresponds to the conflict IDs used in the UCDP/Prio Dataset and the
UCDP Dyadic dataset.

bc_namestring. Name of the conflict, same as listed in the UCDP database and
UCDP/Prio Dataset

country1

text. In case of intrastate conflict, the name of the country where thegovernment is being challenged or where a territory is being claimed. In case ofinterstate conflict, the name of one of the states involved in the conflict.

country2

text. In case of intrastate conflict, this value is empty (NULL). In case ofinterstate conflict, the name of the other state involved in the conflict.

location1

numeric (3-digit positive integer). Numeric country code corresponding tocountry1 variable. The country codes in use correspond to those used by the9UCDP External Support Project // Primary Warring Party Dataset Codebook, v. 1.0-2011

UCDP database, UCDP Actor Dataset, UCDP/Prio Dataset and UCDP Dyadic
Dataset and are compatible with the country codes employed by the Correlatesof War Project and to those used by the Gleditsch and Ward Interstate System.
location2

numeric (3-digit positive integer). Numeric country code corresponding tocountry2 variable. The value of the variable is empty (NULL) if the value ofcountry2 is empty (NULL). The country codes in use correspond to those usedby the UCDP database, UCDP Actor Dataset, UCDP/Prio Dataset and UCDP
Dyadic Dataset and are compatible with the country codes employed by theCorrelates of War Project and to those used by the Gleditsch and Ward
Interstate System.

bwd_idnumeric (4-digit positive integer). The unique identifier of the dyad in which theprimary warring party is involved, as listed in the UCDP Dyadic Dataset.

bwd_name

text. The name of the dyad in which the primary warring party is involved, as
listed in the UCDP Dyadic Dataset.

external_exists

dummy variable (missing values coded as -1). The variable takes the value of 1 if
a primary warring party/receiver of support received any form of clearly
established external support from one or more external supporter(s) in a given
year.
Additionally, missing/unclear/incomplete values (-1) may contain entries ontypes of support (see below). However, these entries are not complete and,possibly, lack reliability. Significant future work is planned on these entries for
future releases of the dataset.
See also: external_alleged

external_alleged

dummy variable. The variable takes the value of 1 if only alleged support has
been found for a given receiver of support in a given year.
If any clear evidence of external support given to a receiver of support exists fora given dyad in a given year, the variable takes the value of 0.
Thus, even if some external supporters provided, for a given receiver of support
in a given year, clear evidence of external support, while for other external
supporters, there is evidence only of alleged external support; the variabletakes the value of 0.
As such, in all cases where external_alleged is coded as 1, external_exists iscoded as 0. Further, in all cases where external_exists is coded as 1,
10

UCDP External Support Project // Primary Warring Party Dataset Codebook, v. 1.0-2011

external_alleged is coded as 0.
See also: external_exists
external_nametext. The names of the external supporter or supporters providing support to acertain receiver of support in a given dyad in a given year.
Supporters are separated by semicolons, ex. Russia; Spain; Italy; NATO. External
supporters that are only alleged to have provided support are explicitly
mentioned, ex. Iran; Pakistan – alleged; Iraq – alleged.

external_code

text/regular expression. This variable expresses the type of support offered by
all external supporters as a regular expression that can be used by advanced
text-processing and pattern matching tools (such as awk and grep). Each type of
support is expressed in a code formed by the literal identifiers(X,L,Y,W,M,T,$,I,O,U) indicating the type of support given (see section 5.15 fordetails). If the support is only alleged (external_alleged=1), the expression isbracketed. Further, the order the literal identifiers appear in is consistent, being
the one shown above.
The general format of the expression is:external_name1: code of support provided, external_name2: code of support provider,
external_name3: code of support provided…
ex. 1: For the receiver of support FMLN in 1988, the external_code is: Soviet

Union:WMT$, Cuba:WMT$, Vietnam:WMT$, Nicaragua:WMTO. This translates
to: Soviet Union supported FMLN with: Weapons, Materiel/Logistics,
Training/Expertise, Funding/Economic Support. Cuba supported FMLN with: Weapons,
Materiel/Logistics, Training/Expertise, Funding/Economic Support. Vietnam supported
FMLN with: Weapons, Materiel/Logistics, Training/Expertise, Funding/Economic
Support. Nicaragua supported FMLN with: Weapons, Materiel/Logistics,
Training/Expertise, Other forms of support, see comment.
ex. 2: For the receiver of support ULFA in 1994, the external_code is: KNU:W,(Pakistan:T), (Bhutanese Elements:LWT$), (Bangladeshi Elements:LW$). This translates
to KNU supported ULFA with: Weapons. It is alleged that Pakistan supported ULFA
with: Training/Expertise. It is alleged that Bhutanese Elements supported ULFA with:
Access to Territory, Weapons, Training/Expertise, Funding/Economic Support. It isalleged that Bangladeshi Elements supported ULFA with: Access to Territory, Weapons,
Funding/Economic Support.

Note that if you need to process the type of support provided by external
supporters to various receivers of support, it is easier to use the External

Support – Disaggregated/Supporter Level Dataset
external_type_text

text. Contains an English-language description of external supporters together
with the types of support provided by them, for added legibility of the dataset.
Each type of support provided by an external supporter is listed in the cell using
standardized phrasing.
The general format of the text is: (It is alleged that) external supporter 1
supported receiver of support with types of support. (It is alleged that) external
supporter 2 supported receiver of support with types of support….
The 10 standard phrases for types of support are: Troops as secondary warring
party, Access to Territory, Access to military or intelligence infrastructure, Weapons,
Materiel/Logistics, Training/Expertise, Funding/Economic Support, Intelligence material,
Other forms of support, check codebook, Support exists, but is of unknown type.

Note that if you need to process the type of support provided by external
supporters to various receivers of support, it is easier to use the External
Support – Disaggregated/Supporter Level Dataset
For the receiver of support ULFA in 1994, the external_type_text is KNU supported ULFA
with: Weapons. It is alleged that Pakistan supported ULFA with: Training/Expertise. It isalleged that Bhutanese Elements supported ULFA with: Access to Territory, Weapons,
Training/Expertise, Funding/Economic Support. It is alleged that Bangladeshi Elements
supported ULFA with: Access to Territory, Weapons, Funding/Economic Support.

external_comment

Comments on the coding of external support.

5.1 ywp_id : Yearly Warring Party ID
numeric (4-digit positive integer). Ywp_id is a unique year-specific identifier of each primary warring
party (receiver of support).
ex.: Government of Ethiopia, in 1979, has ywp_id of 6469, in 1980, has a ywp_id of 6472, and in 1981, has a
ywp_id of 6475.

5.2 ywp_year: Year of Observation
numeric (4-digit positive integer). Year of observation - The dataset includes all years between 1975 and2009 when a primary warring party/receiver of support is recorded as active in UCDP data, i.e. all years
when the warring party is party to a conflict which reaches the threshold of 25 battle-related deaths.

5.3 ywp_name: Name of primary warring party/receiver of support
text (maximum length: 999 characters). Ywp_name contains the name of the primary warring
party/receiver of support. The variable will reflect on name changes of the group, i.e. will be the namethe group was known by in the coded year.
For state actors, the name given is always ‘Government of…’. For rebel groups the name given is theacronym when applicable. The names are standardized and used in accordance to usage specified in the
UCDP Actor Dataset.
13

UCDP External Support Project // Primary Warring Party Dataset Codebook, v. 1.0-2011

5.4 actorID: ID of the primary warring party/receiver of support
numeric (4-digit positive integer). actorID contains the identifier of the primary warring party/receiver of
support. Each actor in the dataset is ascribed a unique actor ID. For state actors, the Gleditsch and Ward
number for the relevant state is given.
Note that this ID is taken from the UCDP Actor Dataset, which lists all actors recoded in UCDP data onorganized violence.

5.5 bc_id: Conflict ID (UCDP database)numeric (3-digit positive integer). bc_id contains the unique identifier of all armed conflicts in the UCDP
online database.

5.6 conflictID: Conflict ID (UCDP datasets)
numeric (3-digit positive integer). conflictID contains the unique identifier of all armed conflicts in the
UCDP/PRIO Armed Conflict Dataset and the UCDP Dyadic dataset.

5.7 bc_name: Conflict Nametext (maximum length: 999 characters). bc_name contains he name UCDP uses for the armed conflict inwhich the warring party is active.
For intrastate conflict fought over governmental power: name of the state whose government it is thatis being challenged, with the word “government” in parenthesis behind. For example: Ethiopia(government)
For intrastate conflict fought over the status of a specific territory: name of the state where the disputed
territory is located, with the name of the disputed territory in parenthesis behind. For example: Ethiopia(Ogaden)
For interstate conflict: the names of the two (or more) states that have an incompatibility with a dash in
between. For example: Eritrea – Ethiopia

5.8 bwd_id: Dyad ID
14

UCDP External Support Project // Primary Warring Party Dataset Codebook, v. 1.0-2011

numeric (4-digit positive integer). The unique identifier of all dyads active in interstate or intrastatearmed conflicts (i.e. dyads included in the, UCDP database and UCDP Dyadic Dataset). The dyad id listed
is that of the dyad which contains a given primary warring party/receiver of support.

5.9 bwd_name: Dyad Nametext (maximum length: 999 characters). bwd_name The name that UCDP uses for a dyad which contains
a given warring party.
The name of the party on side A, and the name of the warring party on side B, with a dash between. For
example: Government of Ethiopia – ONLF. The name of the state actor is always first in the dyad name.

5.10 external_exists: External Support Exists
dummy variable (missing values coded as -1). The variable takes the value of 1 if a primary warring
party/receiver of support received any form of clearly established external support from one or more
external supporter(s) in a given year.
Additionally, missing/unclear/incomplete values (-1) may contain entries on types of support (seebelow). However, these entries are not complete and, possibly, lack reliability. Significant future work isplanned on these entries for future releases of the dataset.

5.11 external_alleged: External Support is Alleged
dummy variable. The variable takes the value of 1 if only alleged support has been found for a given
receiver of support in a given year.
If any clear evidence of external support given to a receiver of support exists for a given dyad in a given
year, the variable takes the value of 0.
Thus, even if some external supporters provided, for a given receiver of support in a given year, clear
evidence of external support, while for other external supporters, there is evidence only of alleged
external support; the variable takes the value of 0.
As such, in all cases where external_alleged is coded as 1, external_exists is coded as 0. Further, in allcases where external_exists is coded as 1, external_alleged is coded as 0.

5.12 external_name: Name of External Supporter
text. The names of the external supporter or supporters providing support to a certain receiver of
support in a given dyad in a given year.
Supporters are separated by semicolons, ex. Russia; Spain; Italy; NATO. External supporters that are only
alleged to have provided support are explicitly mentioned, ex. Iran; Pakistan – alleged; Iraq – alleged.
Names are similar to those used in the UCDP Actor Dataset, with the following differences:--

In case of governmental supporters, the particle ‘Government of’ has been dropped. Standardized
forms are used for a number of states, such as United States, Soviet Union, East Germany, West
Germany, North Korea, South Korea, North Yemen, South Yemen and United Kingdom.
The names of supporters, as used in the current dataset, are the names of both states and nonstate groups as were current in the year when they provided external support.

5.13 external _code: External Support Code / Regular Expression
text/regular expression. This variable expresses the type of support offered by all external supporters asa regular expression that can be used by advanced text-processing and pattern matching tools (such asawk and grep). Each type of support is expressed in a code formed by the literal identifiers(X,L,Y,W,M,T,$,I,O,U) indicating the type of support given (see section 5.15 for details). If the support isonly alleged (external_alleged=1), the expression is bracketed. Further, the order the literal identifiers
appear in is consistent, being the one shown above.
The general format of the expression is:external_name1: code of support provided, external_name2: code of support provider, external_name3: code of
support provided…
ex. 1: For the receiver of support FMLN in 1988, the external_code is: Soviet Union:WMT$, Cuba:WMT$,Vietnam:WMT$, Nicaragua:WMTO. This translates to: Soviet Union supported FMLN with: Weapons,
Materiel/Logistics, Training/Expertise, Funding/Economic Support. Cuba supported FMLN with: Weapons,
Materiel/Logistics, Training/Expertise, Funding/Economic Support. Vietnam supported FMLN with: Weapons,
Materiel/Logistics, Training/Expertise, Funding/Economic Support. Nicaragua supported FMLN with: Weapons,
Materiel/Logistics, Training/Expertise, Other forms of support, see comment.
ex. 2: For the receiver of support ULFA in 1994, the external_code is: KNU:W, (Pakistan:T), (Bhutanese
Elements:LWT$), (Bangladeshi Elements:LW$). This translates to KNU supported ULFA with: Weapons. It is allegedthat Pakistan supported ULFA with: Training/Expertise. It is alleged that Bhutanese Elements supported ULFA with:
Access to Territory, Weapons, Training/Expertise, Funding/Economic Support. It is alleged that Bangladeshi
Elements supported ULFA with: Access to Territory, Weapons, Funding/Economic Support.

with types of support. (It is alleged that) external supporter 2 supported receiver of support with types of
support….
The 10 standard phrases for types of support are: Troops as secondary warring party, Access to Territory,
Access to military or intelligence infrastructure, Weapons, Materiel/Logistics, Training/Expertise,
Funding/Economic Support, Intelligence material, Other forms of support, check codebook, Support exists, but isof unknown type.

Note that if you need to process the type of support provided by external supporters to various
receivers of support, it is easier to use the External Support – Disaggregated/Supporter Level Dataset
For the receiver of support ULFA in 1994, the external_type_text is KNU supported ULFA with: Weapons. It isalleged that Pakistan supported ULFA with: Training/Expertise. It is alleged that Bhutanese Elements supported
ULFA with: Access to Territory, Weapons, Training/Expertise, Funding/Economic Support. It is alleged that
Bangladeshi Elements supported ULFA with: Access to Territory, Weapons, Funding/Economic Support.

5.15 external_type_{literal: X,L,Y,W,M,T,$,I,O,U}: Variables identifying the type of support received by
the primary warring party/support receiver
Ten separate dummy variables.

In this dataset UCDP divides external support in 10 separate categories, depending on what was received
by the primary warring party/support receiver. Each of these categories are identified by a name and aliteral identifier (a one-letter code, used in the names of the dummy variables covering each type of
support, and in the regular expression provided in the external_code). These ten types of support are:5.15.1 Troops as secondary warring party (Literal: X):
This type of support indicates that a state has sent combat troops to fight alongside a primary warring
party. This category corresponds to what UCDP in other places call secondary warring support.
17

UCDP External Support Project // Primary Warring Party Dataset Codebook, v. 1.0-2011

Note that this does not apply to troops sent as technicians in support of equipment sent or loaned(which would be coded as M-Materiel/logistics or W-Weapons), or to military trainers, military
specialists, planners, experts etc. (which would be coded as T-Training/Expertise).
Further, this DOES NOT covers joint ops or alliances between non-state entities, or between a non-state
external supporter and a government primary warring party or if the secondary supporter is engaged on
its own in a conflict with a common enemy (it is then coded as Y–access to military and intelligence
infrastructure).
The dummy variable corresponding to this type of support is external_type_X.
5.15.2 Access to military or intelligence infrastructure / Joint Operations (Literal: Y):
This type of support is coded when a supporter allows a warring party to use its own military
infrastructure as if it would be integrated within the warring party’s chain of command. This translates
in the external supporter permitting the primary warring party, in some way or another, to use somepart of their military infrastructure (bases, intelligence gathering stations etc.) as if it were their own,
while stopping short of sending troops to fight alongside the primary warring party.
Alliances between rebel groups and joint operations by two governments against a rebel group, where
each of the two governments is a primary warring party in two separate conflicts against that same nonstate group are also counted as Y-Access to military or intelligence infrastructure.
Examples of support coded as Y-Access to military or intelligence infrastructure include treaties
allowing for joint intelligence operation, such as Plan Condor, a joint coordination effort by the militaries
of a number of South American dictatorships with a goal of eliminating leftist groups, leases of bases
belonging to the external supporter or joint co-ordination/planning of operations by two rebel groups.
The dummy variable corresponding to this type of support is external_type_Y.
5.15.3 Access to territory (Literal: L):
This type of support covers support, by which an actor allows a warring party to set bases on the
territory it controls, permits sanctuary or cross-border military action for the supported warring party orin any other way concedes its full sovereignty in favor of a supported party.
Access to territory is only coded when it is clear that the support was intentional. Subsequently, in the
many states in Sub Saharan Africa or South Asia where borders are very porous and there is no or very
limited control in densely forested or desert areas, it is not enough to find evidence that a group for
instance had bases on a ‘supporter’s’ territory, but actual proof of intent is needed.
The dummy variable corresponding to this type of support is external_type_L.
5.15.4 Weapons (Literal: W):
18

UCDP External Support Project // Primary Warring Party Dataset Codebook, v. 1.0-2011

Support covered here includes donations, transfers, supplies or loans of weapons or ammunition of any
kind. Sales on conciliatory terms (such as deferred payments, offsets beyond what could be expectedunder terms of standard commercial agreements) are included in this category.
Note that this variable is not coded for sales of weaponry between governments in accordance tostandard commercial terms.
The dummy variable corresponding to this type of support is external_type_W.
5.15.5 Materiel/Logistics Support (Literal: M):
A range of different types of support is covered in this variable. Typical support covered by this category
include non-weaponry and non-ammunition supplies that are used in conjunction with direct military
operations and serve direct military purposes (vehicles, uniforms, tents, field hospitals, etc.). This
includes technology that is not directly a weapons system (radars, night vision technology, construction
bulldozers etc.).
Also included is logistics assistance (including troops transport), as well as repair and support facilities
for advanced weaponry (such as aircraft, rocketry, tanks), including technicians or operators of such.
The dummy variable corresponding to this type of support is external_type_M.
5.15.6 Training/Expertise (Literal: T):
This variable covers training of any kind, both in situ and in the supporter’s country. Furthermore, expert
personnel and foreign military advisers present at HQ level or not directly engaged in combat operations
are included in this category of assistance.
The dummy variable corresponding to this type of support is external_type_T.
5.15.7 Funding/Economic Support (Literal: $):This type of support covers any form of economic aid that was extended by an external supporter inorder to be used to fund the waging of the armed conflict or is given to the warring party. This includes
military loans, military grants, and military/defense to be used towards improving the capabilities of themilitary. This also includes intercession or support in front of multilateral financial institutions (such as
the WB or the IMF) or other lenders.
Note that this type of support typically does not include humanitarian, development or balance of
payments aid/loans.
The dummy variable corresponding to this type of support is external_type_$
5.15.8 Intelligence (Literal: I):

19

UCDP External Support Project // Primary Warring Party Dataset Codebook, v. 1.0-2011

This form of support covers any form of intelligence material presented by an external supporter (mapsregarding positions of the enemy, cryptographic codes and keys, satellite imagery, signals intelligence ofany kind, information on troop capability, data on whereabouts of rebel leaders etc.).
Note that this includes only information provided as such by the external supporter. If a supporter gives
the warring party the possibility to utilize (at will) the capacities of the supporter’s intelligence
infrastructure (i.e., gives access to a primary party to use a satellite to gather intelligence as they see fit),
this is coded as Y-Access to military or intelligence infrastructure.
The dummy variable corresponding to this type of support is external_type_I
5.15.9 Other Forms of Support (Literal: O):
This form of support includes types not covered in the previous categories, such as e.g. recruitment
opportunities, running, harboring and/or funding a radio station belonging to a rebel group,intermediating transfers of weaponry, etc.
The dummy variable corresponding to this type of support is external_type_O
5.15.10 Unknown type of support (Literal: U):
This form of support is coded when reliable sources talk of support but do not specify of what type.
The dummy variable corresponding to this type of support is external_type_U.

5.16 external_comment: Comments on external support.
text. This variable contains freeform comments included by the coders. The field could containcontextual information of various kinds, historical data, magnitude or level of support, the overall effectthe support had on the conflict, coding information etc.
