after a Roman ambush near Antigonia. Roman Emperor Julian was mortally wounded in an ambush near Samarra in 363 during the retreat from his Persian campaign. A Byzantine invasion of Persian Armenia was repelled by a small force at Anglon who performed a meticulous ambush by using the rough terrain as force multiplier and concealing in houses. Heraclius' discovery of a planned ambush by Shahrbaraz in 622 was a decisive factor in his campaign. Arabia during Muhammad's era According to Muslim tradition, Islamic Prophet Muhammad used ambush tactics in his military campaigns. His first such use was during the Caravan raids. In the Kharrar caravan raid, Sa`d ibn Abi Waqqas was ordered to lead a raid against the Quraysh. His group consisted of about twenty Muhajirs. This raid was about a month after the previous one.

A Muslim who happened to pass that way found him and assisted him to return to Medina. The raid was unsuccessful. Procedure In modern warfare, an ambush is most often employed by ground troops up to platoon size against enemy targets, which may be other ground troops, or possibly vehicles. However, in some situations, especially when deep behind enemy lines, the actual attack will be carried out by a platoon, a company-sized unit will be deployed to support the attack group, setting up and maintaining a forward patrol harbour from which the attacking force will deploy, and to which they will retire after the attack. Planning Ambushes are complex multi-phase operations and are therefore usually planned in some detail. First, a suitable killing zone is identified. This is the place where the ambush
