I wonder which 120mm round they have to lift? There’s as much as 15lb difference between the lightest and heaviest types of rounds. Ex the M829 armor-piercing sabot round is 41 pounds, while the M829A3 sabot is 56lb (uses a DU sabot instead of aluminum).
Good point - I think the dummy rounds used for this test are 52 lb HEAT simulated. I’ve never lifted a DU round, since I was never in combat....but that extra weight would surprise people for sure.
