Note: The M2 .50 caliber machine gun is still standard issue today. Mr. Browning's magnificent weapon may see its 100th birthday, still on active duty.

The .50 caliber machine gun is primarily an anti-vehicular weapon. Its weight, and the weight of its ammunition, make it unsuitable for mobile infantry use. However, in semi-fixed positions such as the MLR in Korea, or mounted on vehicles in file, as in the withdrawal from Chosin, the weapon is magnificent. Its great range and striking power make it deadly in enfilade against troops staging for assault. Again, these capabilities make it ideal for quick reaction against machine gun and mortar positions on heights overlooking road communications.

Against massed infantry attack over ground with relatively constant slope, as against the Chinese human wave assaults on our MLR such as at Vegas, the M2 is a truly terrible force. For mobile patrol deployment, mounted on light vehicles, it is equally effective.
