I think he mentioned that it was aimed shots and not just maximum rate of fire. I believe the ammo had to be in the racks as they were trying to get as close to combat conditions as possible. |

Will have to see if they have worked out the bugs as I believe that the new M1A3 is going to be a diesel-electric. |
