Clearing out a building that had another faction in it. With Monolith everyone is an enemy to them, so easy to figure out who is friend or foe. Real simple, Monolith equals friend. Not Monolith equals enemy. Military occupy the building and I go room to room clearing them out capturing the point on the map. I find its best to travel to areas the troops are having troubles capturing. And by helping them the area usually gets secured. I have been completely overrun and found myself leaving the area, even with five or so troops following me.
In this case I have it under control and take out the few army guards that show up. And once secured Monolith spawn in, and by the time around a dozen or so troops are on the base its good to go on its own.. Usually, of course that changes sometimes. Especially when I was not playing as Monolith. Found myself going back all the time to re-secure areas as the Monolith flood hit my base defenses.
I found myself an AK but its pretty beat up and I find it jamming quite a bit. Though my pistol is kept up and I can quickly switch to it if I jam my primary gun while in a battle. Eventually I find to find a decent rifle and get one thats at 100% repair status so jams arent so common.
