That Scorp looks fantastic! Is it too late to join? Was a Centurion tankie, but my particular model (Sh'ot Mk.4) isn't out yet by AFV Club, so, if OK, I'd build a Revell Merkava III, as I was there during the transition to the Merkava III, and the Revell kit has the right badge for my unit. I never actually drove a Merkava III although, just saw them, and watched the 120 smooth bore being fired at night (an amazing sight!).
If not, I flew in a Herc, and guarded AH-64As (got to know them very well), and worked with the crews of AH-64A and F-16 A&B (and sat in the cockpit of an F-16A!), been in jeeps, command cars, trucks, and Gawd knows what else! I could even justify, just, a Hotchkiss 2 seater or a T-62, as we had both examples on my base, or, the earlier Sh'ot, as mine was a development of these earlier ones, and AFV Club do produce one of those.
