Hardened sentry bot

Hardened Sentry Bots are robots encountered in Fallout: New Vegas. They are encountered along with Hardened Mr. Gutsys at the Crashed Vertibird. The best way to take them down is with the Pulse Gun. its takes three shots to take them down.

Oddly enough, they have 0 DT despite being "hardened". What appears to be high DT is the result of very high health.
