Ammo count is currently broken. Upon starting the game you have no ammo count until you've selected a "mini" which I'm assuming can be subbed for any NPC. It appears that your ammo will also disappear randomly throughout the game as well. When selecting allied marines with your ammo count being visible, the ammo amount will stack as though you had selected multiple units and their inventory overlays are being stacked. There is apparently no maximum limit to the amount of stacking ammo counts. Can also display the ammo count of other marines in real time.
