Halo 2A M6C

Adds the Halo 2A M6C Magnum chambered in 10MM auto in accordance with UNSC standard practice.

It was a common practice among soldiers to tell their shore-leave lays that their standard issue sidearm shot the powerful 12.7 x 40mm round wielded by the legendary Spartan super soldiers. Whether this was to impress them with their strength or to make them feel closer in skill to a spartan was never truly figured out. However, this caused a widespread misconception that the standard-sized handgun fired a round that punched far above its weight class. This caused numerous weapon malfunctions among lower-level enlisted as they would try to force the larger bullets into their magazines, sometimes succeeding but only due to the double-stacked nature of these magazines. This led to many soldiers having their weapons jammed tight and without ammunition in the rare cases they would have to rely on it. Alternatively, this myth caused soldiers to overestimate their sidearm and engage with it rather than their much more powerful battle rifles. This left the brass extremely confused as to how their troops could believe that their small M6C could ever chamber, much less safely fire, the massive rounds of the M6D. After these strange occurrences, the M6C was recalled and issued solely to groups of elite ODST units in a new suppressed SOCOM format. This also prompted the UNSC to include a 100 level geometry class as a required course to complete basic training.
