Invincible Helicopters On Operation Firestorm

Unsure if its cheats, bugged, or intentional but me and my buddy were launching TOW's at an attack chopper and clearly landing them, mentioned it in the chat, shortly after the chat mention, hit markers from machine gun started actually showing and the next TOW worked, I have it clipped for player name reference. Another player achieved a 1 shot, 600 damage tank kill against me hitting frontal armor, i believe it was a different player also, however didn't catch that username. Seems fishy, or perhaps I made a mistake somewhere, couldn't screenshot that in time though. Hopefully its desync of some sort, really hoping javelin was worth the trouble of setting up secure boot.
