Armor

Armor is flat dmg reduction. Mitigation is flat armor reduction. If a bullet with 50 damage and 10 mitigation hits a character with 20 armor, it will do 40 damage.Units lose armor equal to 15% of the damage they take before armor reductions. All sources of damage shred armor equally. Shotguns can kill an andron, it will just take more than 6x as long.Effectively, mitigation is damage that is ignored if the enemy has next to no armor and does not contribute to shred.Shotguns are bad at piercing armor primarily because they do lots of small attacks, not because of their low mitigation. This also means they're good after armor is shredded. Thus you should fire sniper rifles before shotguns. Unless the shotgun doesn't have enough power to do damage even after the sniper rifle shreds the enemy, then you should fire the shotgun first to effectively deal 15% of that damage to their HP each time a bullet which actually deals damage hits. Or don't fire at all, cuz 15% is really low.
