CMSR covers the skills and fitness needed to survive and operate in a field environment, and seeks to imbue the ethos and principles of the British Army.
The trainee is required to demonstrate competence in thirteen training objectives over the fourteen-week course.
Officers undertake the Commissioning Course, which covers the basic aspects of soldiering as well as command, leadership and management.
Module A consists of basic field training and elementary military skills.
This can be completed at either a University Officers Training Unit (UOTC) over a number of weekends, or over two weeks at the Royal Military Academy Sandhurst (RMAS).
Module B covers training in Tactics, Leadership, Doctrine and Navigation, both in theory and in practice, with a focus on the section battle drills and the platoon combat estimate.
CBRN training is also added at this point, and Officer Cadets undergo a number of field exercises to test their military and leadership skills.
Based at the RMAS, this module consists primarily of a prolonged field exercise, followed by drill training in preparation for the passing out parade.
Special To Arm training is specific to the type of unit the subaltern is joining, and covers a two-week period.
