Security Suggestions.

[Roomba]

Nuke ops get mentioned a lot when it comes to buffing armory firepower, but honestly whenever nuke ops win it's rarely if ever due to straight-up outgunning the station with superior firepower, and if sec really pulls together and makes use of all the resources it has, it outclasses anything the ops bring to the table. Plus any increase in armory firepower is a double-edged sword that's more likely to be nabbed by an enterprising emagger/wiz than for 'legitimate' purposes. Really the only situation in which lasers straight up beat shotguns are for a rampaging changeling in full abomination mode but that's super rare.

I think more defensive items might be of use but I'm iffy on that riot shield one, even after all the weaknesses described total immunity to bullets seems iffy.
