The initial uses of the Black Box would, according to FN, be in logistics and maintenance. The in-gun shot counter would keep track of how many rounds were being fired, updating a future soldier's digital comm/puter system - Land Warrior or some similar rig - as it went, using some form of wearable networking.

Not only would the soldier then know automatically how many shots he had fired without the need to keep count or look at his magazines and pouches, but so would his team leader - and higher commanders would be warned in advance if their people seemed likely to run out of ammo.

Of course, that's not much use if you're a British soldier and don't actually have any ammo left

Not so much Dredd, more Rogue Trooper.
