"{Withdraw} Armory."
At my words the Pelican Protectors dropped onto the floor of my room. Unlike in video games not many militaries had a single soldier carry many weapons without good reason. Normally those would be for specific roles, such as shotguns for door breaching, ordinance to take down tanks or a backup assault rifle for snipers.
Even the notion that every soldier carried a secondary pistol was false. While that may be true for the front lines, those on stand by or guard duty had no need for the extra weight. Having a gun didn't end with just the gun itself. You also needed the ammunition.
I now had the same problem. I had twelve guns from the armory. But they had a number of calibers. The question would be how much of each should I carry and why?
For large firearms, I had the M60 and M24 which both fired 7.62×51mm NATO. The AR15 which used 5.56×45mm NATO, and lastly a Winchester 1887 shotgun which fired 10 Gauge slugs or buckshots.
