The Marine Aerospace Division is a specialty branch of the Union Marines tasked with any and all flight duties in the Marines' mission profile. Unlike their Naval Aerospace Arm peers, the pilots and crews of MAD have as an explicit goal to get as close to the action as possible — to close with the enemy, or the engagement, whether it be ground, sky, or space — and apply direct fire support. Wherever Marine combat units go, they are able to summon an awaiting MAD unit to provide fire support, observation, bombardment, reinforcement, or extraction.
