BrickArms RPG-7 Rocket Grenade
CAD $1.44
The portable tank-destroyer. The warhead packs a wallop and can take out a Sherman, or an APC!
Versatile, the BrickArms RPG can be used as a Panzerfaust for taking out the Shermans, or even as a modern RPG against an armored personnel carrier. You could even buy two, and cut the warhead off of one of them for that "just-fired" look.
