query: What changes were planned for the Organized Marine Corps Reserve in the late 1960s?
answer: In late 1965, a plan was approved to reorganize the Organized Marine Corps Reserve so the division/wing team would become a "mirror image" of its regular counterparts.  This involved reorganizing the 4th Marine Aircraft Wing, establishing division combat and combat support units, forming the 4th Force Service Regiment (completed in June 1968), and forming FMF augmentation units. Active duty colonels were assigned as commanders of reserve regiments, reserve brigadier generals as assistant division commanders, and an active duty general officer as full-time division commander.
