The M992A2 FAASV is a U.S. tracked ammunition support vehicle built to accompany M109-family self-propelled howitzers, especially the M109A6 Paladin. It carries separate-loading 155 mm projectiles, propellant charges, fuzes, and crew under armor, uses powered handling equipment to transfer rounds at the gun line, and appears in Ukraine transfer and service reporting under the broader M-992/M992 FAASV designation.
SIPRI records 30 U.S. M-992 FAASV armored supply vehicles ordered for Ukraine in 2022 and delivered in 2023 as second-hand aid after Russia's full-scale invasion. Ukrainian Military Pages and Army Recognition separately reported M992 FAASV vehicles in Ukrainian service from social-media imagery, with Army Recognition placing one in the Zaporizhzhia area with Ukraine's 47th Separate Mechanized Brigade; that fielding evidence remains direct but image-derived.
Role detailsThe FAASV is not a firing vehicle; its combat value is keeping a tracked howitzer section supplied without forcing crews to expose loose ammunition in the open. In the M109A6 section, the vehicle provides protected storage, powered handling, and rearming moves between the firing point and ammunition source.
M109A6 Paladin and other M109-series self-propelled howitzers.
Projectile racks, storage compartments, an auxiliary power unit, and a hydraulic conveyor for single-round transfer.
SIPRI records M-992 FAASV transfers to Ukraine, while public service evidence comes from open-source reports of photographed M992 FAASV vehicles. U.S. aid releases identify ammunition support vehicles but do not name the M992A2 in that package.
The FAASV line moved from the original M992 through A1 and A2 modernization, then into the M992A3 Carrier, Ammunition, Tracked vehicle paired with the M109A7.

| M1050 | Proposed FAASV derivative for M110-series 203 mm artillery | Forecast International says BMY developed M992 and M1050 concepts, but the U.S. Army did not procure M1050 FAASV or Fire Direction Center variants. |
The FAASV exists to keep tracked artillery batteries supplied with separate-loading ammunition while crews and ammunition remain under armor.
