On 11-21-23 Chicago Engine 91 landed at 2701 N Pulaski with a fire in a 1-story warehouse. After about 15 minutes, Battalion 7 pulled all companies out, pulled a box, and went defensive. I arrived about 25 minutes into this fire. Engines 91, 76, 7, 69, 56, 43, 68 from what I saw were all pumping handlines and supplying aerial master streams to Tower Ladders 23, 14, 21, and Squad 2.
