A missile encampment on the mountainside. The missiles rapid-fire.
Gundampilotspaz: I still don't know why they even bother.
thewayneiac: Okay, it never works, but I guess they might as well try shooting at the Angel on general principle.
Hexon.Arq: Maybe Japan's current frontman and/or his buddies are making money off of that stuff getting wasted… hint, hint. (Dated America 2004)
Dr. Nick: Note that this and other stationary gadgets are Nerv's own defense system, whereas (armed) mobile things like tanks and planes belong to the UN / JSSDF. In EoE, Nerv's using those same defenses as they're trying to hinder the army from advancing, but we never see Nerv using tanks or attack choppers of their own. If I had to guess, I'd say all of Nerv's own vehicles are unarmed (sure, they do have the frigate, but I assume it's stripped of its armaments).
