This section of the gallery contains six albums of patches worn by graduates of the various training programs for missileers and others, some of which are or have been mandatory, and others of which are optional, and even highly selective. The albums, ordered alphabetically, are for the ICBM Weapons Instructor Course (WIC), Missile IQT/IST, Officer Space Prerequisite Training (OSPT), Undergraduate Space and Missile Training (USMT), Weapon Intern Program (WIP), and Other Training Classes. Some of these training programs have been discontinued. To the maximum extent possible, patches in each of the albums are presented in chronological order.
