Hell Let Loose - Kursk is Great!

What a great map. Seriously, it's excellent. Unfortunately, I have been headshot through log piles, and I have also been headshot through trees on Hurtgen. Just like that intro clip, I have shot enemies multiple times at close range, with a Kar98 and haven't killed them. One time on Omaha Beach, I stood over a prone enemy, slowly aimed onto his head and shot him twice, and he didn't die, and then turned around and killed me. So there is still something weird happening with the hit boxes.

What's your favorite weapon on the Russian faction?
