Model 2 Sidearm

The Model 2 sidearm is the main secondary weapon of the Confederate Marine Corps.

Design
The M2 is not a ballistic weapon, but a directed enrgy weapon. After the Human-Covenant War, the design of the UNSC weapon known as the Spartan laser was evaluated by human and Covenant to make the design more effeicient. They were successful, and by the 2600s many military firearms used directed energy.
