Using that method I managed to squirrel away NVGs, FAKs, and a nifty little Night Scope I picked up somewhere. It won't work if you're going to switch bases, but it's something at least. Then I get my essential kit, go pick up my bag, and head out. You do so, hear the briefing, and then get teleported to the armory. You go up to the officer or whoever, he lets you know there is a mission on and gives you an actionmenu option to join. Then I drop any extra gear, such as launchers, into the box. I found that when you return from a mission you still have all your gear, so I've gotten into the habit of loading my nice captured CSAT backpack (that has lots of extra room) on the ground inside the base after loading my NVGs, GPS, FAKs, etc.
You're not supplied with NVG (I don't know if you can loot them around), and it's hard to travel and shoot once it gets really dark.
