Ok. I just want to get this out of my system once and for all. THE FUCKING ROCKETS EXPLODE AND KILL YOU IF IT GOES OFF 2 INCHES FROM YOU. Ahh..that feels better. Here are some videos. Notice the immediate blast radius. The immediate area isn't necessarily the only kill zone either as shrapnel expelled from the blast can kill you for quite a ways.
WW2 Panzer on tank
WW2 Panzer on open field
Educational - Bazooka/Piat/Panzerfaust/Panzerschrek
Please note the high explosive power around where the shell impacts. The fact that it was used to take down buildings. Pierce AND explode.
