Several units have found out the hard way it’s not a good idea to leave the M153 common remotely operated weapons station (CROWS) II locked at maximum elevation for travel.
If a weapon is installed on CROWS and CROWS is locked at maximum elevation (60 degrees), the weapon’s barrel can reach as far as 5 1/4 feet above the vehicle, depending on the weapon. At that height, the barrel can collide with overhead objects like cables and overpasses. Something is going to be damaged big time.
Unless you’re operating CROWS, lock CROWS to the lowest elevation for travel. That puts CROWS and the weapon only 30 inches above the vehicle.
