Like I mentioned, I still got a bunch of my old Engineer manuals, with plenty of good reference drawings of mines and explosives, plus a few odd ones like battlefield sensors and "hypothetical" ADMs (aka, the nuke looks like this and makes this big a boom, but we aren't actually admitting it exists). I think the utitily of a "Bouncing Betty" in a Poser scene would be rather limited, though. The apocryphal story of the guy with the baseball bat notwithstanding.
