Selfless Commitment. This is what the British Army has to say about it: On joining the Army soldiers accept an open-ended commitment to serve whenever and wherever they are needed, whatever the difficulties or dangers may be.uch commitment imposes certain limitations on individual freedom, and requires a degree of self-sacrifice. This may involve, for example, long periods of separation from family and friends, the disruption caused by a move at short notice, and the carrying out of regimental guards and duties.
