While the shotgun might not be the most practical weapon to serve in combat roles anymore, there is no denying how critically important it can be in a fight. This is a weapon that is very lethal when used in the right hands, especially when being used to breach a locked door. There is little question about whether the shotgun is here to stay and whether future forms will only be more aggressive.
Why We’re Writing About American-Made Military Shotguns
For over a century, military shotguns have been a key tool for American soldiers, helping them to breach doors, clear trenches, and maintain an upper hand in close-quarters combat. Examining the shotguns used by the U.S. military can provide insights into the complex relationships between government spending, major defense contractors, and global conflict.
Are Shotguns Effective in Combat?
A shotgun isn’t the preferred long arm for most military engagements. However, urban fighting and close-quarters combat do see some use for the humble shotgun. With the right loads, American troops can shred the enemy with ease.
Versatility
Part of what makes a shotgun a viable combat weapon is versatility. A 12 gauge pump action can load slugs, buckshot, and breaching rounds, which give it a combination of combat lethality and the means of safely entering buildings all in one handy package.
