I found an old note from my father, Warren Miller ( RA16126494 )  I should know this, but does “MM” mean “medium maintenance” ?

“After serving with advancing troops in WWII through North Africa, Sicily, Italy, Corsica, and Southern France where my unit the 410th Anti-Aircraft 90MM Gun Battalion was de-activated. Re-activated as the 407th MM Ord Company of the 101st Airborne Division, my unit supported the 63rd Infantry Division moving through Alsace France and into Germany. In the early days of May probably 5-6 May 1945 my company "rumbled" into the small village of Hardheim Germany (south of Wurzburg Germany) and halted as the war came to an end.”

thanks-
