Opinion on Tiger Model M1A2 Abraams SEP kit

I have not built it, but have seen some nice builds of it.  It looks to be a pretty good kit.  As to color, it can be done in either NATO camo (large pic) or in CARC Tan (desert color) as in the smaller pic below it.

While I'm not familiar with this kit, there truly isn't a "desert version" per se. The same basic Abrams can be fitted with TUSK I or II armor or none at all.

This one has TUSK I armor (tank urban survival kit) with the original reactive armor bricks. TUSK II has the scalloped ceramic tiles.
