That's right, this is a 5-in-1 kit! Trumpeter has compiled parts from five of its M1 kits under one big boxtop so you can build one of any of these five versions of the US Abrams MBT: an M1A1HA, an M1A1HA with mine roller, an M1A1HA with TWMP, an M1A2, or an M1 Panther II. Tracks are provided as one-piece flexible belts or injection-molded link-and-length assemblies. The turret and upper hull feature good anti-slip surface detail. While there's nothing really new included in this kit, it's still nice to have all the options in one box...and of course, your spares box will be full of goodies after you build one of the versions in the kit!
