Sri Lanka Army The Sri Lanka Army ( " Sri Lanka Yuddha Hamudawa " ) is the oldest and largest of the Sri Lanka Armed Forces and is responsible for land - based military and humanitarian operations . Established as the Ceylon Army in 1949 , it was renamed when Sri Lanka became a republic in 1972 . As of the year 2010 , the Army has believed to have approximately 200 , 000 regular personnel , approximately between 20 , 000 – 40 , 000 reserve personnel and 18 , 000 National Guardsmen and comprises 13 operational divisions , one air - mobile brigade , one commando brigade , one special forces brigade , one independent armored brigade , three mechanized infantry brigades and over 40 infantry brigades . From the 1980s to 2009 the army was engaged in the Sri Lankan civil war . The professional head of the Sri Lanka Army is the Commander of the Army , currently Lieutenant General Daya Ratnayake . The Commander - in - Chief of the Sri Lankan Military is the President of the country , who heads the National Security Council through the Ministry of Defense , which is the highest level of military command charged with formulating , executing defence policy and procurements for the armed forces . However operations of the Sri Lanka Army are coordinated by the Joint Operations Command , with other two armed forces . History . Ancient and pre - colonial times . The first military engagements in Sri Lankan history were marked by the advent of King Vijaya , a Bengal prince who landed along with his followers on the beaches of northwestern Sri Lanka around 543 BC . Prince Vijaya and his followers occupied the lands of the native Veddah people . Repeated incursions by South Indians , particularly the Chola s , into Sri Lankan territory occurred throughout the next few centuries and led to the engagement of the rival forces in battle . In one famous encounter , Sinhalese King Dutugemunu ( 200 BC ) raised an army of eleven thousand inhabitants in his battle against the Chola invader King Elara , whom he eventually defeated . King Dutugemunu ' s organizational skills , bravery and chivalry are famous and his battles have gone down in history as outstanding offensive operations . Other Sri Lankan rulers whose military achievements stand out include King Gajabâhu ( 113 AD ) , who sailed to India to bring back his captured soldiers , and King Dhatusena ( 433 ) who is credited with repulsing numerous Indian invasions and for organizing a naval build - up to deter seaborne attacks . He also had the foresight to cover his defenses with artillery . Vijayabâhu I ( 1001 ) was another warrior king who dislodged Indian invaders and united the country . Parakramabahu the Great ( 1153 ) was an outstanding monarch of the Polonnaruwa period of Sri Lankan history , and his accomplishments as a military leader and a great administrator are noteworthy . His reign included a military expedition to Burma ( Myanmar ) in retaliation for indignities inflicted on his envoys and Burmese interference in the elephant trade . This marked the first overseas expedition in Sri Lankan military history . It is also reported that Parakramabahu ' s fame was such that his assistance was sought by South Indian rulers who were involved in internecine struggles . Another strong ruler in the pre - colonial era was Parâkramabâhu VI , who defeated Indian invaders , united the island and ruled it from capital Sri Jayawardhanapura , Kotte . Although the known epigraphical records do not indicate that the Sri Lankan rulers had a full - time standing army at their disposal , there is evidence supported by legend , designation , name , place and tradition that prove there were ' stand - by ' equestrian , elephant , and infantry divisions to ensure royal authority at all times . Militias were raised as the necessity arose , and the soldiers returned to their pursuits , mainly for farming , after their spell of military duty . Colonial era . Parts of Sri Lanka came under the control of three colonial European powers , namely the Portuguese in the 16th century , the Dutch in the 17th century and the British in the 18th century . Yet , until the entire island was ceded to the British in 1815 , regional kingdoms maintained most of their independent defense forces and were able to successfully repulse repeated thrusts by the European armies . However the British , unlike their counterparts , were not primarily restricted to maritime power , and thus had the capability to bring the entire island under their control and to integrate locals into the British defense forces . Portuguese and Dutch rule ( 1505 – 1796 AD ) . In the beginning of the 16th century , modern Europe first came in contact with Sri Lanka , which was then referred to as Ceylon . In 1505 a Portuguese fleet , while operating in the Indian seas against Arab traders , was blown off course and landed at Galle , on the southern coast of the island . In 1517 the Portuguese re - appeared , and with the consent of the Sinhalese King established a trading post in Colombo . Having initiated contact with Sri Lanka as traders , the Portuguese soon made themselves political masters of the western seaboard . Numerous forts were soon established , and features of European civilization were introduced . The Portuguese are credited with the introduction of European - style fortresses to Sri Lanka during this era . Although some locals already possessed military training and fighting experience , there is no evidence that the Portuguese employed local inhabitants into their own forces . Thus the Portuguese were forced to restrict their presence in the island due to their small numbers and their efforts were more focussed toward projecting maritime power . In 1602 Dutch explorers first landed in Sri Lanka , which was then under Portuguese control . By 1658 they had completely ousted the Portuguese from the coastal regions of the island . Much like the Portuguese , they did not employ locals in their military , and preferred to live in isolation , pursuing their interests in trade and commerce . Like the Portuguese , they defended their forts with their own forces , but unlike the Portuguese , Dutch forces employed Swiss and Malay mercenaries . The Dutch Forts in Jaffna , Galle , Matara , Batticaloa and Trincomalee were sturdily built and are considered a tribute to their military engineering skills . Also , like the Portuguese , the Dutch focussed on maritime power and although they had the capability to develop and use local forces , they chose to isolate themselves from the local population . British rule ( 1798 – 1948 AD ) . The British Empire then ousted the Dutch from the coastal areas of the country , and sought to conquer the independent Kandyan Kingdom . In the face of repeated British assaults , the Kandyans were forced into a degree of guerrilla warfare and fared well against their superior British adversaries . Initially the British stationed their forces , which included naval vessels , artillery troops and infantry , to defend of the island nation from other foreign powers , using the natural harbor of Trincomalee as their headquarters in Sri Lanka . In 1796 , the Swiss and Malay mercenaries who were previously in the service of the Dutch were transferred to the British East India Company . While the Swiss De Meuron ' s Regiment was eventually disbanded in Canada in 1822 , the Malays , who initially formed a Malay Corps , were converted into the 1st Ceylon Regiment in 1802 and placed under a British commanding officer . In the same year , the British became the first foreign power to raise a Sinhalese unit , which was named the 2nd Ceylon Regiment , also known as the Sepoy Corps . In 1803 the 3rd Ceylon Regiment was created with Moluccans and recruits from Penang . All these regiments fought alongside British troops in the Kandyan wars which began in 1803 . Throughout the following years , more Sinhalese and Malays were recruited to these regiments , and in 1814 the 4th Regiment was raised , which was composed entirely of African troops . It was later renamed as the Ceylon Rifle Regiment . Eventually , the Kandyan Kingdom was ceded to the British in 1815 , and with that they gained control over the whole island . Resistance to British occupation cropped up almost instantly . During the first half - century of occupation , the British faced a number of uprisings , and were forced to maintain a sizable army in order to guarantee their control over the island . After the Matale Rebellion led by Puran Appu in 1848 , in which a number of Sinhalese recruits defected to the side of the rebels , the recruitment of Sinhalese to the British forces was temporarily halted . The second phase in the employment of non - British personnel commenced in 1881 after the enactment of an ordinance designed to authorize the creation of a Volunteer Corps in the island . It was designated the Ceylon Light Infantry Volunteers ( CLIV ) . This move compensated for the disbandment of the Ceylon Rifle Regiment in 1874 . The Ceylon Light Infantry Volunteers was originally administered as a single unit . However , over the years various sections of the volunteers grew large enough to become independent from their parent unit . The different units that emerged from the Volunteer Force were the In 1910 the name of the military was formally changed to the Ceylon Defence Force ( CDF ) . It continued to grow throughout the early period of the 20th century . The CDF saw active service when a contingent of the Ceylon Mounted Infantry ( CMI ) in 1900 , and a contingent of the Ceylon Planters Rifle Corps ( CPRC ) in 1902 , took part in the Second Boer War in South Africa . Their services were recognized by the presentation in 1902 of a color to the CMI , and a presentation in 1904 of a banner to the CPRC . In 1922 , the CDF was honored by the presentation of the King ' s and Regimental colors to the Ceylon Light Infantry ( CLI ) . During the First World War , many volunteers from the Defence Force traveled to England and joined the British Army , and many of them were killed in action . One of them mentioned by Sir Arthur Conan Doyle was Private Jacotine of the CLI , who was the last man left alive in his unit at the Battle of Lys , and who continued to fight for 20 minutes before he was killed . In 1939 , the CDF was mobilized and an enormous expansion took place which required the raising of new units such as the Ceylon Signals Corps , the Auxiliary Territorial Service ( Ceylon ) and also the Colombo Town Guard , which had been previously disbanded , but was later re - formed to meet military requirements . During the Second World War , Britain assumed direct control over the Armed Forces of Ceylon . Post - independence . At the end of World War II , CDF which had increased in size during the war began demobilization . In 1948 Sri Lanka gained independence from Britain , becoming a Dominion within the commonwealth and a year earlier Ceylon entered into the bi - lateral Anglo - Ceylonese Defence Agreement of 1947 . This followed by the Army Act No . 17 of 1949 which was passed by Parliament on April 11 , 1949 and formalized in Gazette Extraordinary No . 10028 of October 10 , 1949 marked the creation of the Ceylon Army , consisting of a regular and a volunteer force , the later being the successor of the disbanded CDF . Therefor October 10 , 1949 is considered the Ceylon Army was raised , and October 10 is celebrated annually as Army day . The Defence Agreement of 1947 provided the assurance that British would come to the aid of Ceylon in the event it was attacked by a foreign power and provided British military advises to build the country ' s military . Brigadier James Sinclair , Earl of Caithness was appointed as general officer commanding Ceylon Army , as such becoming the first commander of the Ceylon Army . The initial requirement was to raise an artillery regiment , an engineer squadron , an infantry battalion , a medical unit , and a service corps company . For much of the 1950s the army was preoccupied with the task of building itself and training existing and new personal . To this aim the British Army Training Team ( BATT ) advisory group carried out training for ex - members of the CDF within the Ceylon Army , senior officers were sent to the British Army Staff College , Camberley and some attached to units of the British Army of the Rhine to gain field experience . New officers were sent for training at Royal Military Academy , Sandhurst which continued until the 1960s and both officers and other ranks were sent to specialist training courses in Britain , India , Pakistan and Malaya . There were no formations and all units were structured to directly function under the Army Headquarters . However temporary field headquarters were to be formed at the time requirement arose . Due to a lack of any major external threats the growth of the army was slow , and the primary duties of the army quickly moved towards internal security by the mid - 1950s , the same time as the first Ceylonese Commander Major General Anton Muttukumaru took command of the army . The first internal security operation of the Ceylon Army began in 1952 , code named " Operation Monty " to counter the influx of illegal South Indian immigrants brought in by smugglers on the north - western cost , in support of Royal Ceylon Navy coastal patrols and police operations . This was expanded and renamed as Task Force Anti - Illicit Immigration ( TaFII ) in 1963 and continued up to 1981 when it was disbanded . The Army was mobilized to help the police to restore peace under provincial emergency regulations during the 1953 hartal , the 1956 Gal Oya Valley riots and in 1958 it was deployed for the first time under emergency regulations throughout the island during the 1958 Riots . During the 1950s and 1960s the army was called apron to carry to essential services when the workers went on strike which were organized by the left wing parties and trade unions for various reasons , the most notable was the 1961 Colombo Port strike , during which ships threatened to bypass Colombo port and the country almost staved . To counter these common strikes several units were formed , who were employed in development work when there were no strikes . In 1962 several volunteer officers attempted a military coup , which was stopped hours before it was launched . This attempted coup effect the military to a great extent , since the government mistrusted the military , it reduced the size and growth of the army , especially the volunteer force , with several units being disbanded . In May 1972 , when Ceylon was proclaimed a republic and changed its name to from the Dominion of Ceylon to the Republic of Sri Lanka , all Army units were renamed accordingly . 1970 – Present . After successfully defeating the insurgency led by the Janatha Vimukthi Peramuna ( JVP ) in 1971 , the army was confronted with a new conflict , this time with the Liberation Tigers of Tamil Eelam ( LTTE ) and other Tamil militant groups . The war escalated to the point where India was asked to intervene as a peacekeeping force . This was later seen as a tactical error , as the Indian Peace Keeping Force united nationalist elements such as the JVP to politically support the LTTE in their call to evict the IPKF . The war with the LTTE was halted following the signing of a ceasefire agreement in 2002 with the help of international mediation . However , renewed violence broke out in December 2005 and following the collapse of peace talks , the Army has been involved in the heavy fighting that has resumed in the north and east of the country . Since 1980 the army has undertaken many operations against the LTTE rebels . The major operations conducted by the army eventually led to the recapture of Jaffna and other rebel strongholds . In 19 May 2009 Sri Lankan army declare the victory of war as they found the dead body of LTTE leader Velupillai Prabhakaran . This marked the end of the war , with the LTTE ceasing to exist in Sri Lanka as a result of prolonged military offensives conducted by Sri Lanka army . Peacekeeping . The Sri Lanka Army has taken part in two peacekeeping missions with United Nations over the course of its history . First assignment was in the Congo ( ONUC ) ( 1960 – 1963 ) . Most recently , following the signing of a ceasefire agreement was signed between the government and the LTTE in 2002 , Sri Lankan forces were invited by the United Nations to be part of the UN peacekeeping force in Haiti . In the process of the peacekeeping operations , two soldiers were killed in a raid in Petit - Goave . < ref name = " sdut - 3 / 21 / 05 " > < / ref > After over 6 months of service , the first contingent of the peacekeeping force returned to Sri Lanka on May 17 , 2005 . In December 2007 , 7th rotation of the Sri Lankan contingent had been deployed with a force of 991 officers and other ranks , many of the those deployed have been awarded the United Nations Medal for their services . In November 2007 , 114 members of the 950 member Sri Lankan Army peacekeeping mission in Haiti were accused of sexual misconduct and abuse . 108 members , including 3 officers of the 950 - member - strong Sri Lanka peacekeeping contingent is being sent back after being implicated in alleged misconduct and sexual abuse . UN spokeswoman Michele Montas said : " The United Nations and the Sri Lankan government deeply regret any sexual exploitation and abuse that has occurred . " The Sri Lankan Officials claim that there is little tangible evidence on this case . After inquiry into the case the UN Office of Internal Oversight Services ( OIOS ) has concluded ‘ acts of sexual exploitation and abuse ( against children ) were frequent and occurred usually at night , and at virtually every location where the contingent personnel were deployed . ’ The OIOS is assisting in the pending legal proceedings initiated by the Sri Lankan Government and has said charges should include rape " because it involves children under 18 years of age " . Current deployments . As of present , the bulk of the Sri Lankan Army is deployed for domestic defensive and combat operations , while a sizable foreign deployment is maintained . Domestic . Due to the Sri Lankan Civil War the army has been on a constant mobilized ( including reservist ) state since the 1980s ( except for a brief period from 2002 – 2005 ) . The majority of the army as been deployed in the North and Eastern provinces of the country , which includes 14 Divisions coming under six operational headquarters and 2 independent Divisions and several independent Brigade s . The army is also based in other parts of the island for internal security including a Division for the defense of the capital . Foreign . The Sri Lanka Army currently participates in several major overseas deployments : Organization Structure . The professional head of the army is the Commander of the Army , at present Lieutenant General Daya Ratnayake . He is assisted by the Chief of Staff of the Army , currently Major General Krishantha Silva . The Commandant of the Volunteer Force is head of the Army Volunteer Force and is responsible for the administration and recruitment of all reserve units and personal . The Army Headquarters , situated in Colombo is the main administrative and the operational headquarters of the Sri Lanka Army . Administrative . The Army Headquarters is divided into a number of branches , namely the General Staff ( GS ) branch responsible for coordination of operations and training and the Adjutant General ' s ( AGs ) branch responsible for personal administration , welfare , medical services and rehabilitation . The Quarter Master General ' s ( QMGs ) branch is responsible for feeding , transport , movement and construction and maintenance . The Master General of Ordnance ' s ( MGOs ) branch is responsible for procurement and maintenance of vehicles and special equipment . The Military Secretary ' s Branch is responsible for handling all matters pertaining to officers such as promotions , postings and discipline . Each branch is headed by an officer in the rank of Major General who is directly responsible to the Commander of the Army for the smooth functioning of the Branch . Under each Branch , there are several Directorates , each headed by a Brigadier . The Headquarters of field formations each have its own staff . For instance a divisional headquarters is divided into a GS branch as an AQ branch , each headed by a Colonel and is responsible for operations & training and administration & logistics respectively . Similarly , a Brigade Major and Major AQ is responsible for operations and administration in a brigade . Like the Indian Army , the Sri Lanka Army has largely retained the British - style regimental system that it inherited upon independence . The individual regiment s ( such as the Sri Lanka Light Infantry and the Sinha Regiment ) operate independently and recruit their own members . Officers tend to remain in a single battalion throughout their careers . The infantry battalion , the basic unit of organization in field operations , includes five companies of four platoons each . Typical platoon have three squads ( sections ) of ten personnel each . In addition to the basic infantry forces , a commando regiment was also established in 1986 . Support for the infantry is provided by an armoured regiment , five reconnaissance regiments , three mechanized infantry regiments , five field artillery regiments , a rocket artillery regiment , three commando regiments , three special forces regiments , six field engineering regiments , five signals battalions , a medical corps , and a variety of logistics units . Operational Command . Organized and controlled by the Army General Staff at Army HQ , various formations are raised from time to time to suit various security requirements and operation in the country and overs seas . The Army at present has deployed 12 Divisions , 7 task force s and several independent brigade s . Except for the 11 Division based at the Panagoda Cantonment which is responsible for the maintenance of capability for the defence of the capital , all other divisions , task forces and brigades are deployed for operations in the Northern and Eastern provinces of Sri Lanka , coming under six regional commands known as " Security Forces Headquarters " , which are the Security Forces Headquarters Jaffna ( SFHQ - J ) , Wanni ( SFHQ - W ) , East ( SFHQ - E ) , Kilinochchi ( SFHQ - KLN ) , Mullaittivu ( SFHQ - MLT ) & South ( SFHQ - S ) Each SFHQ and most divisions are commanded by a General Officer Commanding in the rank of Major General . A SFHQ has several divisions under its command and each division is further divided into brigade s . Each brigade is commanded by an officer in the rank of Brigadier and has a number of Infantry battalions , support arms ( Artillery , Engineers and Signals ) and support services ( Service Corps , Engineering Services , Ordnance Corps , Electrical and Mechanical Engineers ) under assigned to it . There are also several independent brigade ( Air Mobile Brigade , Armored Brigade , etc . ) In other parts of the country , there are Area and Sub - Area Headquarters . Armour , Artillery , Engineers and Signals Units are grouped under Brigade Headquarters of their own arm ; Armored Brigade , Artillery Brigade and so on . Training . General Sir John Kotelawala Defence University ( KDU ) formed in 1981 and situated in Ratmalana , fourteen kilometers south of Colombo , is Sri Lanka ' s only university specializing in defense studies . Each year , approximately fifty cadets from all three services are admitted to the university ( aged 18 – 22 ) to participate in a three - year program of academic work and basic training . Junior field officer s of the army and their counterparts in the Navy and Air Force are given advanced training and education at the Defence Services Command and Staff College ( DSCSC ) at Batalanda , Makola which was established in 1997 as the " Army Command and Staff College " . Basic officer training is carried out at the Sri Lanka Military Academy ( SLMA ) ( formally the Army Training Center ) situated in Diyatalawa , in the Badulla District . The officer cadets graduating from the academy are commissioned as officers in the regular and volunteer forces . The course for officer cadet s runs for ninety weeks and includes training in tactics and administration which helps prepare the cadets to take up the positions of platoon commanders . The course consisted of military and academic subjects and also trained the cadets physically . The course helps to promote leadership qualities and the understanding of each one ’ s role as an officer and a servant of the state . Due to the lack of officers within the lower levels , the training process was sped up in the 1980s by developing a short commission course . The cadets were given a training of fifty - six weeks and devoted themselves to continue their careers in the military with the ten years of service for regular army officers and five years of service for volunteer officers . Training for the new recruits are carried out by the Army Training School in Maduru Oya at several locations followed by additional training ( both officers and other ranks ) at the Infantry Training Centre in Minneriya , the Combat Training School in Ampara , while non - commissioned officer s receive training at the Non - commissioned Officers Training School at Kala Oya . All these establishments come under the control of the Directorate of Training , Army Headquarters . Specialist and additional training is given by specialist training schools , regimental training centers and individual field units . As the armed forces of Sri Lanka have a limited indigenous training facilities , especially in advanced roles , they have depended greatly on military training provided by foreign countries . The United Kingdom played a major role in the early years following independence and have continued to be an important source of military expertise to the Sri Lankan military . Other sources include India , Australia , Malaysia , Pakistan , and the United States . Additionally , in an agreement reached in 1984 , Israeli security personnel ( reportedly from Shin Bet , the Israeli counterespionage and internal security organization ) trained army officers in counterinsurgency techniques . The Sri Lankan Army has also provided special training to the United States Army on their request as well as many other countries in military education regarding civilian rescue , jungle combat , and guerilla warfare etc . Training establishments . Training Centers Regimental Training Centers Personnel . The Sri Lanka Army presently stands at 200 , 000 strong including 2 , 960 women plus and 58 , 000 reservists . In late 1987 , the army had a total estimated strength of up to 40 , 000 troops , about evenly divided between regular army personnel and reservists on active duty . The approximately 20 , 000 regular army troops represented a significant increase over the 1983 strength of only 12 , 000 . Aggressive recruitment campaigns following the 1983 riots raised this number to 16 , 000 by early 1985 . by 1990 the had army expanded to over 90 , 000 and By 2007 , it had expanded to over 120 , 000 personnel . Since the Sri Lankan armed forces are all volunteer services , all personal in the Sri Lanka Army have volunteered as regular personnel or reservists . This should not be confused with the traditional term " volunteers " used for reservists or reservist units . Recruitment of the personal are carried island wide with a restrictions in the norther and eastern provinces during the civil war in those areas . The Rifle Corps is the only territorial unit that carries out recruitment from a specific area . In June 2009 , Sri Lanka announced plans to create a " Tamil regiment " to promote integration in the army Parama Weera Vibhushanaya recipients . The Parama Weera Vibhushanaya is the highest award for valour awarded in the Sri Lankan armed forces . Army recipients include ; Notable fallen members . Over 23 , 790 Sri Lankan armed forces personnel were killed since begin of the civil war in 1981 to its end in 2009 , this includes 11 general officer s killed in active duty or assassinated . 659 service personnel were killed due to the second JVP insurrection from 1987 to 1990 . 53 service personnel were killed and 323 were wounded in the first JVP insurrection from 1971 to 1972 . Notable fallen members includes ; Women in the Sri Lanka Army . The Sri Lanka Army Women ' s Corps ( SLAWC ) was formed on September 1 , 1979 as an unarmed , noncombatant support unit . Set up with the assistance of the Women ' s Royal Army Corps , it was identical in structure to its parent organization , and its first generation of officer cadets was trained in Britain . Candidates were required to be between eighteen and twenty years old and to have passed the General Common Entrance ( Ordinary level ) examinations , while the Officer candidates must have passed the Advanced Level . Enlistment entailed a five - year service commitment ( the same as for men ) , and recruits were not allowed to marry during this period . In the sixteen - week training course at the Army Training Center at the Diyatalawa Sri Lanka Military Academy , cadets were put through a program of drill and physical training similar to the men ' s program , with the exception of weapons and battle craft training . Female recruits were paid according to the same scale as the men , but were limited to service in nursing , communications , and clerical work . In late 1987 , the first class of women graduates from the Viyanini Army Training Center were certified to serve as army instructors . But , from late 1987 – after hostilities began , the first batch of women graduates from the British Army ' s Women ' s Corp Center certified to serve as Army Instructors . Up to now , women officers have proved their ability and serve in varied specialized fields in the Service as control tower operators , electronic warfare technicians , radio material teletypists , automotive mechanics , aviation supply personnel , cryptographers , doctors , combat medic , lawyers , engineers and even aerial photographers . To meet the operational requirements in the field areas , the 2nd Volunteer Battalion of the Women ’ s Corps was also raised . A few officers from the regular counterpart were attached to this unit to organize the command structure . They are currently employed in active combat duties in the northern and eastern parts of the island . Many officers commencing with Lieutenant Colonel A . W . Thambiraja were appointed to command this unit from time to time . The first women ’ s corps officer to command the unit was Lieutenant Colonel Kumudini Weerasekara in 1992 and as of 2007 there were three female officers of the rank of Major General . At present there is one regular regiment and four volunteer regiments in the Women ’ s Corps . Equipment . In the 1980s , the army expanded its range of weapons from the original stock of World War II - era British Lee Enfield rifle s , Sten Submachine guns , Vickers machine gun s , Bren machine guns , 6 - inch coastal guns , Daimler Armoured Car s , Bren Gun Carriers , 40 mm anti - aircraft guns , 3 . 7 inch heavy anti - aircraft guns and 4 . 2 - inch heavy mortars as well as post war Alvis Saladin s , Alvis Saracen , Ferrets and Shorland S55 s . New sources of weaponry in the mid - to - late 1970s included the Soviet Union , Yugoslavia , and China – countries with which the leftist Bandaranaike government had close ties . China continued to be an important source of arms well into the 1990s . To meet the threat posed by predominantly the LTTE , Army purchased modern military hardware including 50 - caliber heavy machine gun s , rocket - propelled grenade ( RPG ) launchers , Night Vision Device s , 106 mm recoilless rifles , 60 mm and 81 mm mortar s , 40 mm grenade launcher s and some sniper rifle s . Refurbished armored personnel carrier s were added to the ' A ' vehicle fleet of the 1st Reece Regiment , Sri Lanka Armoured Corps . These APCs enabled the Armoured Corps to have their own assault troops to provide close contact protection to their Alvis Saladin and Ferret Scout Cars which were vulnerable to anti - tank weapons . The capability of the Sri Lanka Artillery was enhanced with the introduction of Ordnance QF 25 pounder s . Chinese - made 122 mm , 130 mm and 152 mm howitzers were introduced to the Sri Lankan Army in 1995 and 1998 whilst 122 mm Multi Barrel Rocket Launchers ( MBRL ) , were first used in 2000 by the Sri Lanka Army . Though the weapons were obsolete at the time of purchase , the Government security forces found them to be successful in combat . Land mines proved to be the most lethal threat to the security forces , as many mines have been deployed against government forces by the LTTE in the Northern and Eastern Provinces . These mines were deployed with normalcy against government trucks and buses , with a high rate of casualty . These land mines weighed approximately 50 – 100 kg , against which no armoured vehicle that the SLA possessed was able to withstand the blast effect . Therefore the South African made Buffel was introduced to service in 1985 to reduce damage due to land mines . By 1987 the Army ' s own Unicorn was also developed to a level so that they too matched the capabilities of the Buffels from South Africa , this was followed up by the newer Unibuffel class . Both the Unicorn and the Unibuffel are assembled by the Sri Lanka Electrical & Mechanical Engineers . In recent years , Sri Lanka has become increasingly reliant on China for weapons . This is due to most European nations and the United States Governments passing regulations about the selling of weaponry to nations which are suffering from internal conflict . However in light of recent attacks by the LTTE , the United States has expressed its intent to maintain military training assistance and possibly increase it should the violence continue . Sri Lanka also continues to receive a variety of weapons from Britain , Pakistan , Israel and other former suppliers .
