Play Homefront, you'll get the idea a bit more.

Or....

It looks like a gun/nade/flash etc. will be guaged by points, the better it is the more points. This means you can have anything so long as the points fit. So a nade may be 1 point, AR 3 points, and flash 2 points and so on, its just a matter of making sure you use your points the best.
