This is an issue related to the animation of infantry units being killed. Sometimes, when an infantry unit is killed, their helmet will fly off. Immediately after this, the infantry will transition into a "downed" state, lying on the ground and groaning (this state allows them to be revived by medics). However, during this transition, the helmet that was previously knocked off will instantly reappear on the soldier's head, as if by magic. This sudden "teleportation" of the helmet back onto the soldier's head is very immersion-breaking.

As a casual single-player PvE player, I enjoy observing the gunfights between infantry and the details of the soldiers. This bug is quite frustrating for me. I believe this bug has been present since the game's release. My personal guess is that after the animation for an infantry unit being killed (and their helmet being knocked off) is triggered, there is a chance that the unit transitions into a "downed" state where they can be revived by medics. However, the animation transition between these two states seems to be poorly implemented, causing the helmet to instantly reappear on the downed soldier's head, making the animation look very abrupt and unnatural.

If any developers see my post, I would appreciate a timely response. I hope the relevant developers and maintainers can acknowledge this issue and address the bug.
