I've done a bit of looking, and it appears there are a lot of holes in the needed Cold War offerings for small, wheeled vehicles, in 1/144th (12mm) scale, specifically the following:
M38 Jeep with driver, passenger(s), and MGs. Also needed is one with the 106mm Recoilless Rifle too, for the Danes, Israelis, etc..
M151 Mutt – as above, and with .30 and .50 cal options; a mortar carrier; radio vehicle; 106mm RR; and a TOW launcher.
Landrover (Airborne model with the short wheel-base) with the top and windscreen down, to permit it to mount a .50 cal MG, 106mm RR, and/or TOW launcher.
For the Danes, they need a "Weapons Carrier" for the early/mid Cold War period, which is apparently used to carry around their 81mm mortars. Might be an ex-WWII, US vehicle, but I'm not sure about that – perhaps the 3/4 ton "Weapons Carrier" used by the Americans, back in the day?
West Germans need the Munga. Could use one of these outfitted to carry early ATGMs, like the Bantam, and/or SS-11s. The Iltis would be nice, too.
Of course, the Soviets/Russians need some little "jeep"/command vehicles too. GAZ-XXX perhaps?
Would prefer to see these produced in metal, as opposed to resin, or plastic, and some of the Shapeways listings are going for crazy prices, so are a non-starter for me.
Hopefully, someone will produce at least a few of these in the near future.
Could use some 106mm RRs, TOW Launchers, and .30 and .50 cal MG mounts, with/without crews, and drivers too, for converting other vehicles too, like the M38 Jeeps, HS-30 IFVs, M113s, etc., etc., in the interim.
