Face-meltingly awesome, as always.
Off topic side note- Remember the reach magnum is an M6G, one of two known variants of the M6G (the other variant is the M6G[C] from Halo: 3.) At the time of the Battle of Reach (mid 2552,) the M6B was long retired from the UNSC.
Also, though the MA37 says MA5C on its side, the MA5C was not yet in service during the Fall of Reach, as it entered service after the MJOLNIR Mk. VI.
Your work is still ridiculously freaking awesome, Lee.
