Abrams Tank Systems

Lessons Learned
Operation Iraqi Freedom
2003

Purpose\As with all wars and contingency operations, capturingsystem performance and lessons learned are critical toimproving the systems so we are better able to fulfill thewarfighters requirements\This briefing captures some of the key equipment
performance issues and lessons learned as interpreted by
PM Abram’s personnel deployed forward with the Divisions
during Operation Iraqi Freedom

Topics of Discussion\Armor Protection\Firepower/Target Acquisition\Automotive\Logistics & Sustainment\SummaryProtection\NO catastrophic losses due to Iraqi direct or indirect fire weapons Several tanks were destroyed due to secondary effects attributed to enemy
weapon systems
 Majority of losses attributed to mechanical breakdown and vehicle either being
stripped for parts or severely vandalized by Iraqi people No reported case of an AGTM ever being fired at any U.S. Army vehicle
 No Kornet missiles found in country\Frontal turret and hull armor continues to provide excellent crew protection.
Top, side, and rear armor remains susceptible to penetration
Y Documented instances where 25mm AP-DU and above ammunition disabled a tankfrom the rear
Y Left and right side non-ballistic skirts repeatedly penetrated by anti-armor RPG fireY Cosmetic damage only when struck by anti-personnel RPG rounds
Y No reported hits on ballistic skirts
Y No reported instance of tank hitting an anti-tank mineProtection (cont.)\ Turret ammunition blast doors worked as designed
 Documented instance where turret ready rack compartment hit and main
gun rounds ignited. Blast doors contained the explosion and crewsurvived unharmed except for fume inhalation\ Externally stored items highly vulnerable to small arms fire In some instances, catastrophic losses resulted from burning EAPU material and/orpackaged POL products dripping down into the engine compartment catching theengine on fire Many instances where TA-50 lost or damaged due to enemy fire or secondary affect Lesson Learned – Review and adhere to established load plansProtection (cont.)\ Fear of vehicle/technology compromise led to decisions to destroy
abandoned tanks
 Tanks repeatedly shot by friendly fire, however they NEVER catastrophicallydestroyed the tanks except in one instance Took one thermite grenade, one sabot in turret ammunition compartment, and two
Maverick missiles to finally destroy the tank. Ended up compromising the SAP
armor package during the destruction process Lesson learned – Determine ahead of time what/how much of the tank you wantdestroyed and train crews to execute mission
 Is a sabot in the engine and a thermite grenade in the interior crew
compartment enough?

\ Individual protective equipment worked well
 JLIST suits are much better then the old NBC suits
 CVC’s WILL stop a 7.62 mm round26 March, An Najif - B24, 3-7 Div Cav

Firepower\Overall, very little SABOT was used Devastating effects when used

\Heat and MPAT ended up being the preferred main gun round\Effective against buildings and bunkers

Crew served machine guns ended up being weapon of choice in numerous
engagements
 Target rich environment Iraqis hid in fighting positions until tanks were very near before attacking thus
negating the use of the main gun

Target Acquisition\First Gen FLIR again accomplished the mission but 2nd Gen FLIR needed
to match capabilities of main gun fire control system ranges
 Sand storms made target acquisition difficult

Automotive\APS fleet is not equipped with PJAS. Given the extreme dusty conditions,VPACs required continuous cleaning and servicing by crews. Suspect lackof PJAS contributed to higher rate of engine failure\Suspension Issues
 High rate of failure on #2, #3 and #5 left and right road arms andassemblies
 Under investigation by PM Abrams and GDLS engineers
 Road wheels and track wear proved to be significant over long
distances and high rates of speed

Automotive (cont.)\Rate of movement and maneuvering over vast distances in a shortperiod of time caused units to use more fuel then projected.
Ended up taxing the logistics system\Combat conditions placed a high demand on turret power andrequired continuous scanning. Mixed feedback on use and value
added of external auxiliary power unit

Logistics & Sustainment\Units that deployed with healthy ASL’s and PLL’s faired best
 OPTEMPO of campaign did not facilitate pushing class IX parts forward until
Baghdad secured
 In some instances, critical end items were airlifted forward when weather
permitted
 If unit did not have a required part on hand then the vehicle was stripped of all
usable components and left where it sat\All division level units consistently displayed the inability to send SARRSdata Poor or no visibility on requisition status
 Generally SARRS worked fine but communication links failed due to a variety ofissues\Could not get through fire walls
Software and driver problems
Internet routing protocols

Satellite based communications proving to be the most reliable
form of communications
 Distance and terrain

Logistics & Sustainment\TAP placement and retrograde process
 TAP initially placed at Arifjan (Theater logistics hub). Now placed atBalad airfield north of Baghdad to better support 4 ID and 3 ACR
 LRU/SRU’s that can not be fixed by TAP forward are flown back from
Balad to Arifjan where they are sent back to Ft. Hood for repair.
Estimate minimum 30 day turn around time for replacement LRU/SRU
to arrive back in country

Summary\The Abrams tank preformed extremely well providing
excellent maneuver, firepower, and overall crew protection\Engines typically outlived expectancies and transmissions
proved to be durable\

Specific areas of improvement include: Side and rear armor protection
 Wartime ASL/PLL authorization
 Stowage plans Suspension durability
