Church Army...Seriously WTF?

On a regular basis walking to work I pass a building with "Church Army" emblazoned on the building, I'll be honest this scares the living shit out of me! I immediately get the image of lunatic fundies charging at me automatic weapons (bible verses scrawled on the barrels) blazing. Of course this is mostly just paranoia (I've checked out their website and for an evangelical church they actually seem pretty laid back) but you really have to wonder about a supposedly peaceful organisation that puts "army" right there in the title!
