In both SPMBT and SPWW2, halftracks and APC's 'explode', or 'catch fire' too often to my own estimation. APC's and halftracks generally only carry HMG and MG ammo, which would hardly explode if hit, though the engine may catch fire if hit.
Would tank crews fear a hit to the explosive ammunition tanks carry? This would be no wonder, to my mind, I suppose.
Would increasing the survivability of 'bullet'-carrying vehicles fix this, or to a degree?
For example, if an RPG or similar weapon, like a 40mm grenade, blew through the side of an empty BTR (and possibly the other side), how would this 'knock out' the vehicle?
The engine hit would render the vehicle immobile, surely if it's burning.
I suppose the same would apply to halftracks.
