Looks like a tank to me! D: Is big and can run me over!
I'm gonna get my military nerd on and tell you that's a BMP, it's an amphibious vehicle that's used to shoot everything and everyone and carry people to shoot everything and everyone.
Think of it as a tank's little brother with more choice of ammunition besides BIG BULLET, TINY BULLET.
*Beats Darkness with a T-72 Ural.*
GOD DAMMIT, DARKNESS!!!
The BMP is a MOBILE TREAD, read MOBILE TREAD, vehicle.
WHERE DO YOU SEE TANK TRACKS ON THAT BTR!?
