US Army soldiers recently took the service’s newest 120mm tactical round to the Yuma proving round for a series of trials as part of operational testing.

Two Ivy Division tank crews of the 3rd Armored Brigade Combat Team simulated combat missions with full ready rack combat loads of the XM-1147 Advanced Multi-Purpose (AMP) round for their M1A2 Abrams main battle tanks against a host of actual and simulated threat targets.

“This round is not something to be taken lightly,” said Gunner Sgt. Spencer Vanderbilt, of Charlie Company “Crazy Horse,” 1st Battalion “Fighting Eagles” of the 8th Infantry Regiment.

“Being able to see and then destroy anti-tank guided missile targets beyond 2,000 meters and then transition immediately to breaching walls or obstacles is an incredibly powerful feeling!”

“We now know what it feels like to roll out in a fully combat loaded tank on operationally realistic combat missions and recognize how important the AMP round will be to US Army ABCT fighting forces in the fights yet to be fought,” added Hall.

Capabilities of the AMP round included the new airburst mode and breaching double reinforced concrete walls.

The Crazy Horse armored crews shot over 90 AMP rounds at anti-tank guided missile teams, massed infantry, infantry fighting vehicles and bunker targets.

Test Team Master Gunner Vehicle Crew Evaluator Master Sgt. Joel Ramirez, of the Fort Hood, Texas-based US Army Operational Test Command said the purpose of the operational testing is to collect performance data and soldier feedback to inform the Army’s procurement decision regarding the AMP round.

“We do this by having the tank crews employ the tactical service round in a manner and in an environment that closely mimics combat conditions,” said Ramirez.

He went on to explain how the 3rd ABCT tank crews shot over 8 complex modified tank gunnery combat scenarios during the four-day record test.

“Despite extreme desert heat, dust storms and rain squalls, the Crazy Horse crews really impressed me with their level of motivation and drive to test the AMP round,” said Mr. Kent Evans, the Maneuver Requirements Division Soldier and Capability representative from Fort Benning, Georgia.

The XM-1147 Advanced Multi-Purpose (AMP) round was designed to enhance a tank crew’s ability to perform missions with greater lethality and survivability, according to Mr. Jeff McNaboe, lead project engineer, Program Manager for Maneuver Ammunition Systems.

Developed by engineers from Picatinny Arsenal, New Jersey, the Advanced Multi-Purpose (AMP) round is a replacement for four legacy service rounds.
