#4 M1A2 Abrams
Tanks are great. But not all tanks are created equal. The Rhino in GTA V is definitely a fun joyride, but come on – that old thing is nothing compared to the mighty Abrams Main Battle Tank.
So replace it with this highly-detailed model. This Abrams mod includes a bunch of little details that will make war hardware nerds smile: removable equipment bags on the turret, accurately-modeled driver and gunner seats, an optional Tank Urban Survival Kit (TUSK) upgrade, and both the flat desert tan and woodland camo paint patterns.
So now you have a big tank. You know what to do with it.
