MAC round

A UNSC Marathon Class Cruiser firing a dual-MAC

The Magnetic Accelerator Cannon, or MAC, is the primary weapon mounted on UNSC combat ships. By accelerating a depleted uranium or tungsten slug to a fraction of the speed of light, the UNSC is able to physically punch through everything from energy shielding to Forerunner armor plating.

In-game Edit

The MAC is the UNSC's primary weapon, mounted on almost every ship larger than fighters. It operates as the key strength in the UNSC's alpha-strike tactics, however it has a long cooldown. This weapon's Covenant counterpart is the weaker Plasma Torpedo.
