Re: That reminds me...
Iraq really was trying to build a Supergun.
Though I did find it strange that the minor detail that it couldn't possibly work, and would have buckled during assembly, exploded on firing or failed to actually launch a round out of the end didn't seem to matter to anyone.
I mean, while it's pretty good fieldcraft to get your enemy to waste huge resources on a pink or white elephant, I never did work out who played who.
