It's a weapon platform that provides a vast variety of specializations. Short barrels, alternate stocks, long barrels, grenade launchers, shotguns, scopes, red dots, caliber swaps, drum mags, etc etc.

No need to use space-age crazy shit when you can use something that gives EVERYONE the ability to fight to their best ability while at the same time maintaining a mechanical uniformity.

They could swap ammunition, maintain each other's gear, and fulfill each other's roles in a worse case scenario.
