Sacred Haven of Debauchery

Defense? Did someone say DEFENSE?
TANKS! BUILD MORE TANKS!

Please correct me if I'm wrong, but tanks in games are used for attack, while all sorts of defensive structures are used for defense, not counting combat units.

I wouldn't say so; a lean unit can defend itself better.

I respect your point of view, but if you'll allow me to point out: "thin" is not synonymous with "lean." Although I have sometimes encountered such interpretations, mostly coming from thin people themselves, perhaps intended to justify what seems to be a deficiency, i.e., "physical frailty."
