How many 30mm grenades carried?

[atiff]

Hi all,

Been looking at Youtube videos lately, and seeing lots of Iraq and Afghan firefights where guys seem to be popping off half-a-dozen or more 30mm's in a firefight. While I agree you'd use anything to smack the other guy when the heat is on, I wonder how much of their supply they are using up. So... what is a normal load-out for 30mm grenades?

Thanks, Andrew
