5th MSL Battalion, 1st Artillery, 1964 (Source: Hugh Murphy) A slightly closer view of Launcher 2. The rear of the M529 was lowered so the lower booster would clear when moving a missile on or off the RRT. Each RRT also had a 3 KW generator to provide missile heat when in transit during cold weather; although, I never recall using the generators for that purpose. We did crank and operate them periodically.
