One of the best tools for defending your home, pretty much the collapsible spade of the civilians.
Real weapon experts know, that the most dangerous weapon deployed by the German Army is the collapsible spade. It is deadly, multi-purpose, easy to use and hard to destroy. It works against humans, trees, tanks, low-flying aircraft and all kinds of padlocks. And you can dig holes with it, too.
Don't just tell me it works against low-flying aircraft without giving a demonstration. :lol:
