the SMOG-10000 or super heavy mega Mazer orbital gun is a defense cannon made for orbital defense. the original SMOG-9000 was made by a man named "Gerald Ross" aka the triumphant since he led the most successful campaign called the "2nd crusade of expansion" in which he led his army against trillions of luthast citizens that had separated themselves from the empire in 3023 AGW. in one of his battles to take back the malderie system, he attacked a huge part of the enemy fleet in which he was slowed down and almost defeated by an orbital defense gun which destroyed 5 hammerhead battleships, 15 viper class heavy cruisers, and several more ships before being bombarded by a huge portion of the fleet which allowed the fleet to take back the system. seeing this gerelad decided to make an orbital gun of his own. it uses a coil gun layout to fire tracking project tiles which are covered in super heated plasma which means it doesn't have to aim too much just fire and the gravitational pull of luthast will do the rest. the gun always has a decent garrison of 10 dark troopers, 5000 luthast soldats, and several vehicles and ships.
