george,
I built almost all of them except for the Humvees and construction equipment pieces. The containers are Weaver 20 ft ones. The M60A2 is a 1/48 tamiya model no longer in production. LAV25's and LAV-AT are a kit made by Kitech but are out of production since last year. Just got 2 of each from a hobby store in China ( Ebay). The M109's are made by Auroa and were last made in the 70's, I buy them when they come up on ebay. The M2 Bradleys are still around, M1A1 Abrams and M60's are built by Academy and are available. I have about 10 more 1/48 scale kits to build ( 2 Lav25, 2 LAV AT, 2 m1A!, 5 Tamiya Humvees and a 2.5 ton truck). At our club I run a 20 car train either in NATO scheme or a 12 car in desert scheme. I am adding more cars with stuff painted in the desert scheme. believe it or not it is only a fraction of our fleet.
