There was this one time I was on Vidzeme. Our team was doing okay, but eventually we were pushed back to the trenches. Here's where the fun starts. I hop on the AT gun and start scanning for targets. A German Panzer IV Ausf-E comes over the hill, its side facing towards me. I fire, and the tanks blows up, killing all 3 crew members inside. I switch to HE after that, and swiveled to fire at a machine-gun who had been harassing our guys. He was up against those ruins across the brook from the trenches, so I fired against the wall. Turns out there were about 5 Germans lying close to him, because I got about 6 kills out of that.
Later that same round, on the same life (I had gotten off the AT gun because there was a half-track on our right flank and I wanted to kill it with my PTRD) I was lying in the trenches, hiding from the tank that had just appeared on a hill to our right and killed our preoccupied AT gun, when suddenly it started raining grenades. Most of them exploded just outside of the trench, but a few landed in the trench and killed four or so of my buddies. I was miraculously unharmed. Suddenly, six Germans came pouring into the trench. I took aim and started firing wildly with my TT-33. By some miracle, I killed 5 of them (they all came in very close together and were in a sort of disorganized column from my point of view, with only one rank and the side of that rank facing me) before I ran out of ammo. The last one left was a rifleman, and he fired a single shot from the hip at me which missed. Not having time to reload, I got up and ran at him, drawing my TT-33 back to smash him in the face. He did the same, bayonet fixed and pointed at me. Somehow, he missed me and I whacked him in the face with the TT-33, killing him. It was amazing. Nothing like that's ever happened to me again; I've had rambo moments where I've mowed down several Germans with a PPSH-41, or just been a badass for the whole round (the Ultimate Hero and that stuff) but I've never had such a moment happen to me since that round.
In contrast to that, there was that time that I killed our own T-34 with a PTRD.
