Our military adopting the Grendel?

[VASCAR2]

Another thing to consider is rules of engagement and political correctness which weren't near the concern during WWII. In certain conditions in Irag and Afghanistan our troops were not permitted to fire into a building unless they actually saw the insurgent shooting. I know a lot of troops carried armor piercing rounds in their M-1's and I'd say if soldiers came under fire in France in WWII our troops opened up with just about everything they had. In Law Enforcement and Military there appears to be is a lot more concern about hitting civilians (hearts & minds) and non combatants. I've never been in the military but from my LE experience the 5.56/223 is a welcome addition to 38/357, 9MM, 40, 45 and 12 gauge. From my experience the 12 gauge is no better penetrating cars than the 5.56 but if I have to go after an active shooter I'd rather have my 16 inch 5.56 carbine with our issued 55 grain JSP ammo. I haven't read about any failures to stop where the LEO used a 5.56 carbine or rifle. When I started in LE the local departments had a few M-1 carbines and a few mini 14's in the Pd to go along with the shotgun in the cars, now a high percentage of patrol officers carry a 5.56 AR-15 if they so desire. I carried a Remington 870 with slugs as well as my AR-15. Right before I retired from the St. Police my department withdrew our tactical 8 pellet OO buck because of potential of hitting a noncombatants.
