This short illustrated booklet, produced early in the Second World War under War Office guidance, is designed to teach tactics of fighting patrolling to inexperienced officers commanding equally raw recruits. The author is keen to emphasise aggression and maintaining morale - and cautions against splitting the patrol: ' Keep your men together, keep up momentum ( and) you will find yourself enjoying the finest sport on earth'. There are handy hints - and very clear diagrams - on such subjects as street fighting; clearing houses, and synchronisation. Gives a clear idea of the sort of instructions issued to Home Guard and UK Defence forces when a German invasion was expected at any moment.
