I noticed that when you play in MP, with others or AI in the same group the players unit keeps reporting "Ammo low". Even if you carry 10 Mag´s in your vest.

The problem seems to be that ArmA 3 dosent recognizes Ammo clips in the vest.

The ammount in the vest and the backpack should be included before a unit tells "Ammo low" to avoid unnecessary chat during a mission.
