I am currently a Major Grade 1, and i was wondering how you could unlock the security helmet. I'm WAYYYYYYYYYYYYYYYYYYYYY to lazy to to google it (yes, lazier than Stevo) so could somebody just tell me what level you have to be, and how to unlock?
It is available at General, and costs 200,000-250,000 cR if I am not mistaken. You have ways to go, unfortunately. Oh, and based on your name/avatar I see why you want it so much. You have nameplate for Durendal I assume then. Best nameplate out there IMO. Anyway, I'm 99% sure its General with 250,000 cR.
Scorch has you covered, or close enough at least. By the way, each attachment for the security helmet requires higher and higher ranks, so keep that in mind. And too lazy to google it? Kinda sad. LOCKED.
