Non-Commissioned Officer Development Course

LDR 310 · Leadership and Command · Level 300 (intermediate to advanced; corporals and sergeants developing toward senior appointments)

A Royal Army College course on the non-commissioned officer's enduring role: standards, training, welfare, mentoring, and the judgement that carries an NCO toward senior rank.

Course length: 10 hours, studied online and asynchronously at the student's own pace, together with any in-person practical instruction and assessment the course requires.

Foreword

Every army worth the name rests on its non-commissioned officers. Officers command and set direction; it is the NCOs who turn direction into trained, disciplined, cared-for soldiers, day in and day out, and who hold the standards of the whole force in their hands. They are, in the old phrase, the backbone of the Army, and a force is only ever as good as its corporals and sergeants.

This course is for the NCO who has learned to lead a section and is now growing into the wider, deeper role: the corporal becoming a sergeant, the sergeant looking toward the senior appointments. Where the Junior Leadership Course taught the leading of a section, this course teaches the NCO's enduring institutional role across the unit, the keeping of standards, the training of soldiers, the welfare of people, the mentoring of the next generation, the running of the daily business, and the partnership with the officer that makes command work. It is as much about judgement and character matured over time as about any single skill.

It teaches the NCO as the backbone of the Army; the NCO and officer command partnership; the NCO as keeper of standards; the NCO as trainer; the NCO and welfare; mentoring and developing subordinates; managing the routine through administration and organisation; and the mature judgement and long view of the senior NCO.

How this course works

This is an intermediate-to-advanced development course, the next stage of the non-commissioned pathway. Its knowledge is studied online, lesson by lesson, but the NCO's craft is proven in the appointment itself and in the practical and instructional assessments conducted in person. It assumes Foundations of Military Leadership (LDR 201) and builds naturally on the Junior Leadership Course (LDR 301).

Structure

Where this sits

This course sits on the non-commissioned leg of the leadership pathway, above Foundations of Military Leadership (LDR 201) and the Junior Leadership Course (LDR 301). It runs alongside the officer-path Officer Candidate Foundation Course (LDR 401) and feeds the advanced command and ethical-leadership courses (LDR 410 and LDR 420). It draws on Military Customs, Discipline, and Conduct (RMT 120) for standards and discipline, on Physical Training Instructor (FLD 360) and the instructional method for training, and on Caring for Those in Need (HCR 201) for the welfare and the recognition of distress.

A note on sources

This is the College's own course, written fresh in Kaharagian and Commonwealth terms on the British and Commonwealth tradition of the non-commissioned officer, adapting its sources rather than reproducing them. It is written in formal British English and carries Crown Copyright. Its examples are illustrative and use generic settings, since the Principality holds no territory of its own.
