Did Bungie say that or are you just making that up? The G11 assault rifle fires 4.5mm caseless ammunition, and its magazines are not sealed.

If you are referring to the ammo packages on the ground being sealed, that doesn't really make much sense, because all of the human ammunition packages are sealed, regardless of whether or not they are cased.
