Direct Proof Of Ukrainian Fielding
The strongest public evidence for HEAT 551 in this conflict is Ukrainian training and reference material rather than a named battlefield firing. A March 2022 Ukrainian Ground Forces Carl Gustav instruction, hosted by Sprotyv G7, identifies HEAT RAP FFV 551 in the ammunition-recognition section and describes the round as the high-explosive anti-tank rocket-assisted projectile for the 84 mm Carl-Gustaf.
Sprotyv G7's matching online Carl-Gustaf lesson likewise lists HEAT RAP FFV 551, gives its launch-velocity context, and describes it as ammunition for use against armored fighting vehicles. A July 2022 Ukrainian handbook on foreign anti-tank weapons also lists HEAT RAP FFV 551 among the main ammunition types for the 84 mm Carl Gustav launcher.

Timeline
The dated record begins in March 2022, during the full-scale phase of the war, when Ukrainian Ground Forces training material named FFV 551 and included crew carriage and handling context for Carl-Gustaf ammunition. The July 2022 Ukrainian anti-tank weapons handbook then repeated FFV 551 in a broader foreign anti-tank weapons reference, placing it alongside TP RAP FFV 552, FFV 553, and HEDP FFV 502 as ammunition for the 84 mm launcher.

Role In The Conflict
Within the Ukrainian Carl-Gustaf materials, HEAT 551 appears as an anti-armor munition rather than a separately reported weapon system. The Sprotyv G7 lesson describes the M3 Carl Gustav as a platoon anti-tank weapon and says FFV 551 is intended for armored fighting vehicles, while Saab's HEAT 551 fact sheet identifies the round as 84 mm high-explosive anti-tank ammunition with a shaped-charge warhead and 700 m effective range.
The public sources support Ukrainian fielding, training, and anti-armor role context for HEAT 551 in the war. They do not identify a dated battlefield engagement, target, location, unit, or combat firing attributable specifically to HEAT 551 rather than to another Carl-Gustaf round.
