I recently had a west grenadier unit to which I added M9 mags in the unit init. For some reason the M9 mags stack on top of the HE nades in the secondary ammo slots. Not only that, but IIRC I could over stack quite a lot of M9 ammo. Has anyone else noticed this oddity in general or with specific units? And why the hell do HE nades go in sidearm ammo slots?
