137 (Mixed) Heavy Anti-Aircraft Regiment RA (TA) was formed at Newton, Chester in November 1941. The Regiment served in Anti-Aircraft Command until moving to Brussels with 101 Anti-Aircraft Brigade in January 1945. They were the first Mixed AA Regiment to arrive there. Their experience with the static, power operated 3.7’s and the latest Radar and Predictor proved invaluable in shooting down the V 1’s. 137 (Mixed) Heavy Anti-Aircraft Regiment RA (TA) was disbanded in October 1945.
