Wow. 100 rounds seems pretty low to me (although those are just my uneducated "feelings"). I wonder how the troops felt about the amount of ammunition they carried.
Perhaps my perceptions are skewed due to the videos I see on youtube and such featuring engagements in Iraq/Afghan. A number of them contain troops firing streams of 5 - 10 rounds at a time, in which case I do not believe 100 rounds would be adequate at all.
