MAC-10

The Ingram MAC-10, officially known as the M10, is a highly compact, blowback operated machine pistol developed by Gordon B. Ingram in 1964.

Overview
It was first developed in 1964, and was eventually formally adopted into the military by 1970.

During the San Hieronymo Takeover, a MAC-10 with an equippable suppressor was procured by Big Boss's resistance unit at the Power Substation after a Spy Unit located it.

The Peace Sentinels's Escort troops often carried the M10 into battle with them, while escorting various vehicles. Big Boss and his mercenary group, the Militaires Sans Frontieres, later procured design specs relating to the M10 at El Cenegal's swamp while attempting to track Amanda's FSLN unit towards the Banana Fruta de Oro in an attempt to find out if nukes do indeed exist. They later added a suppressor onto it. During a holdup excercise at Bananal Fruita de Oro's Sorting Shed, the MSF also procured design specs relating to a variant of the M10 that utilized a Bullet Jacket and put it into development.

Post-Peace Walker
By 1975, the MAC-10/M10 was removed from the use of the United States Military.

In 2014, the South American rebel soldiers, during their revolution against the current regime, utilized the MAC-10 weapon.
