LDR 420 · Leadership and Command · Level 400 (officers and senior non-commissioned officers)
A Royal Army College course on the gravest ground of command: the commander's answerability for everything done under their authority, and the duty to build a command in which soldiers do right when it is hard.
Course length: approximately 10 hours of online self-study, studied asynchronously at the student's own pace, together with any in-person practical instruction and assessment the course requires.
Foreword
The earlier courses taught that command unites authority with responsibility, and that the responsibility cannot be delegated away. This course takes that responsibility to its hardest edge. A commander is answerable not only for whether the task is done, but for how it is done, and for what their soldiers do and fail to do under their command, including the things the commander never ordered and would never have ordered. That is a heavy doctrine, and it is the settled law and ethic of the profession of arms: the commander who looks away while wrong is done, who builds a command in which cruelty or corruption can take hold, who fails to train and lead their soldiers to act rightly under pressure, is answerable for the result. This course exists so that an officer understands that answerability before they hold it, and learns the leadership that discharges it.
The course is built for a small, lightly armed humanitarian home-defence force, and it does not assume the dramatic moral catastrophes of large wars in order to teach. The pressures that make soldiers act wrongly, fear, fatigue, anger, the example of others, the sense that no one is watching, are present in a flood, a public-order task, a detention, a relief operation among desperate people, as surely as anywhere, and the commander's duty to build a command that holds to the standard under those pressures is the same. What the course teaches is therefore practical: how the ethical climate of a command is built and how it is corroded, what moral courage actually demands of a commander, how toxic leadership poisons a unit, where the limits of obedience lie, how a commander reasons to the right course when it is not obvious, what care a commander owes their own soldiers, how to own outcomes honestly when things go wrong, and how an officer makes their command one in which doing right is the norm and not the exception.
How this course works
This is an advanced course, studied online lesson by lesson, with its case-method seminars and ethical exercises conducted and assessed in person. It assumes the Officer Candidate Foundation Course (LDR 401) or the Non-Commissioned Officer Development Course (LDR 310), and it builds on the ethical leadership of Foundations of Military Leadership (LDR 201) and the law of the commander taught in The Law of Armed Conflict for Soldiers (PME 201). It runs alongside Command, Mission Command, and Decision-Making (LDR 410). It is taught by the case method as much as by instruction: the officer is expected to reason about hard cases and examine their own character against them.

Where this sits
LDR 420 is the second of the advanced command courses, alongside Command, Mission Command, and Decision-Making (LDR 410), above the Officer Candidate Foundation Course (LDR 401) and the Non-Commissioned Officer Development Course (LDR 310). It takes up what the Officer Candidate Foundation Course named in seed, the commander's accountability for all the command does and fails to do, and gives it its full treatment. It rests on the ethical leadership, command climate, and toxic-leadership material of Foundations of Military Leadership (LDR 201), and on the law of armed conflict, command responsibility, and the unlawful order taught in The Law of Armed Conflict for Soldiers (PME 201). It feeds the professional military education courses (PME).
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 profession of arms, the law of command responsibility, and the ethics of military leadership, 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.
