The fuel for nuclear missiles is so toxic that they have to use these space suits when they are working around it.
This plain old standard family van is another Air Force vehicle. Another use for a standard civilian model. Check those model railroad stores for HO scale versions of vehicles like this.
This is the inside of the missile silo. Very cool, and all in a nice pale green and light gray.
Another view of the command center. Photos like this enable the model builder to make unusual subjects for wargaming. During the Cold War there was always the fear that Soviet commandos would raid the missile silos and try to disable the missiles. They had military police on site to prevent this from being successful. To lightly armed elite forces fighting it out over nuclear missiles. Esci, Italeri and Caesar all make good troops to try on a scenario like this one.
