Coastal artillery is the branch of the armed forces concerned with operating anti-ship artillery or fixed gun batteries in coastal fortifications.
Leonard was in the communication branch in the artillery laying wire between batteries between the 90mm anti aircraft guns and their radar.
In anti-aircraft use, the guns were normally operated in groups of four, controlled by the M7 or M9 gun director or Kerrison predictors. Radar direction was common, in 1944, the system was upgraded with the addition of the SCR-584 microwave radar, which was accurate to about 0.06 degrees (1 mil) and also provided automatic tracking.
With the SCR-584, direction and range information was sent directly to the Bell Labs M3 gun data computer, and M9 director, which could direct and lay the guns automatically, all the crews had to do was load the guns.
Leonard spent most of his time in Hawaii except for a short time in the Gilbert Islands to install communications.
