I absolutely love Target Weak Point, medkits, and the sniper Incendiary Explosive Round.
The last one is pretty situational, but I used it yesterday to stop a charging shock + conscript blob. It must have stunned about 10 guys, which gave me the chance to retreat/reposition my units. In the same game I used it on some conscripts that were trying to steal my MG42. With the stun and the sniper's vet 2 increased fire rate I was able to shoot out the 3-man crew before it could pack up and retreat
Just make sure to focus the guy manning the gun!
I always forget about those trip wire flares. I did lose like two snipers to trip wire flares in one game, however, and now they are on my mind again.
