And also, I'm not sure if this is considered a bug or not, but when I saw a garrison access in a room with a sentry hidden at the corner (I was carrying sensor array), I positioned myself at the doorway and fired 2 shots to disable the garrison, believing that the sentry will come after me. Surprisingly, it didn't react at all. (I guess the 24-hour shift is a little to tiring?)
