I have a bad tendency to kill my own team mates thinking to be doing the right thing, just to realise later that perhaps it wasn’t exactly so.
Three situations come to mind, each of which I’ve done more than once (sigh). The first is the above mentioned “Don’t worry I’m just killing you to revive you with full health!! Oops… did you see by any chance where all my limbs go?”. We could call this situation a “Revivus Interruptus”.
Also happened twice to kill a team mate behind a MG, thinking that he’s an enemy shooting at me.
Finally, when I convince myself that the kind guy smiling in front of me is in fact a vicious enemy covert, I apply the “shoot first, ask questions later” principle; I often feel like a fool afterwards… (luckyly I usually play medic, so I can at least try to pretend that I did it to revive him… cough).
Another mistake I make often is trying to revive someone by dropping a grenade on him (hit 4 instead of 5), though i usually manage to actually revive him and flee before the explosion. Fortunately they’re invulnerable for a few seconds so they don’t blow up.
The funniest things I’ve seen anyway happened to other people. Once there was a mortarist outside the forward spawn in oasis, I though “I hope he knows what he’s doing or he could be more use with a medic”. No doubt, the next time I respawn, me and another allie were hit by one of his round. The funny thing is that we were about 2 metres away from him, so it wasn’t us stepping in front of him as he was shooting because he remained unharmed, he must actually have fired with a an elevation of 89° or maybe very low and hit the wall.
Another time, always on oasis (I was axis this time) at some point someone (a very skilled and experienced player, which always beats me in fair duels (ie same hp, no one is surprised/shot from behind)) started complaining that he planted twice at the south anti tank gun but it wouldn’t explode. So I explained to him that it had already been blown up at the very beginning of the game, by a sneaky engineer. Then I ran for the gun to stop him from reaching the north one and planting there. As expected I find him running in the walkway and as soon as he sees me, he tries to kill me… but he couldn’t because he forgot he still had his pliers equipped.
