Opinion on Tiger Model M1A2 Abraams SEP kit

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.

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.
