I left my party members on the presidential level and went to the lower lvl alone so I would not be attacked. i convinced Tom Murray to shut down the reactor. I took the circular stairs in the south of the presidents lvl and ender up in the barracks. The minute I step out of the elevator the freaking robotic turret starts shooting. I did not clear out this lvl when I first entered the enclave so its packed with soldiers! Given that I am alone and wearing advanced power armour should they not leave me alone?
