Ragequit. Following a duel between my M10 Wolverine Tank Destroyer and the enemy Sturmpanzer(their Tank Destroyer). The Sturmpanzer had been nearly crippled, and retreated into their base - itself under heavy mortar bombardment. I flanked my Wolverine to catch it on the side, but the dumbass crew decided to turn the turret to the side to shoot at some cowering soldiers. Even so, it shot up the Sturmpanzer to a tiny sliver of health left. Then it hit it again, and the Sturmpanzer began moving off, looking like it was in the "Out of Control" state which is guaranteed death. I move the Wolverine away to deal with an MG crew that was ghostcapping(and had just killed my jeep). As I'm getting a 105mm howitzer built(the jeep's death gave me pop-cap to build it), and sending a Sherman up the right flank to hit their base, a rifle squad I had on the left flank got torn up by... the Sturmpanzer. It wasn't dead.
I get my Wolverine back into the fray before the Sturm attacked my now-exposed mortar teams. It shoots, and destroys the main gun. Some Pioneers show up to repair, but get scattered by the Wolverine's gun and mortar fire. It keeps firing, seemingly not doing much damage per shot, while itself is about 50%, each hit doing 10%-20%. Then the Sturmpanzer fires, despite not having a lot of repair time(in my experience, critical damage requires a full repair to fix), and it's gun looks visibly damaged. It instantly destroys the Wolverine from 50%.
I tried to build a new one, except they ghostcapped my territory during the duel, knocking out my pop-cap, so I could not build a new one. They, on the other hand, built another Sturmpanzer right in front of my Sherman. That went as well as it was expected to.
Company of Heroes. I wonder where they get the resources to build like that. I capture more than half the map as quick as possible, and generally do a better job holding it, but I had a hard time getting the resources to deploy those troops and tanks. Their Pioneers seem to spawn in with flamethrowers attached, yet I can only equip one Engineer squad with one at the start of the game.
