This is an 8-wide version of the 10-wide M1A2 Abrams model I'd made earlier.
The 8-wide managed to keep almost all of the same details as the 10-wide,
while the 8-wide will actually manage to fit on a train flatbed.  The
way I kept the treads from protruding into the minifig compartment is 
relatively flimsy, as can be seen in the last shot.
