Getting killed by someone with an MP40 hiding around the corner, then when I respawn going there again, hoping to kill him..... from the hip..... with a DP-28 or scoped MN91/30 / SVT-40. Two or three times in a row.
Taking an ISU-152 on Debrecen Brenus 9xcap etc etc. It takes FOREVER to get anywhere, the armour sucks, and while it can one-shot Panthers, even the limited gun traverse you have takes forever and reloading takes forever twice, giving the enemy you just missed by 2 feet at 800m plenty of time to line up his shot and kill me.
Moving while reloading when fighting a Tiger from a T34/76. It doesn't cause them to miss, and it all it does is royally screw up the T34's advantage of much faster reload. And while it does take him three or four shells (as opposed to the ONE Panther shell I usually succumb to in a fucking IS-2) on account of my sloped armour, he does kill me.
All in Red Orchestra, btw. Which should be obvious if you've read some of my other posts.
