The importance of such principles as the use of rugged terrain allowing cover and concealment, the element of surprise, and the quick assault/advance comes down to the present day. 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. 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 will be laid. It is generally a place where enemy units are expected to pass, and which gives reasonable cover for the deployment, execution, and extraction phases of the ambush patrol. A path along a wooded valley floor would be a typical example. Ambush can be described geometrically as: • Linear: when a number of firing units are equally distant from the linear killing zone. • L-shaped: when a short leg of firing units are placed to enfilade the sides of the linear killing zone. • V-shaped: when the firing units are distant from the kill zone at the end where the enemy enters, so the firing units lay down bands of intersecting and interlocking fire. This ambush is normally triggered only when the enemy is well into the kill zone. The intersecting bands of fire prevent any attempt of moving out of the killing zone. To be successful, an ambush patrol must deploy into the area covertly, ideally under the cover of darkness. The patrol will establish secure and covert positions overlooking the killing zone. Usually, two or more ‘cut-off' groups will be sent out a short distance from the main ambushing group, into similarly covert positions. Their job is two fold; first, to give the ambush commander early warning of the approaching enemy, and second, when the ambush is initiated, to prevent any enemies from escaping. Another group will cover the front and rear of the ambush position (blocking force), and thus provide all round defence. Care must be taken by the ambush commander to ensure that fire from any weapon cannot inadvertently hit any other friendly unit (this is known as crossfire). Having set up the ambush, the next phase is to wait. This could be for a few hours, or a few days, depending on the tactical and supply situation. It is obviously much harder for an ambush patrol to remain covert and alert if sentry rosters, shelter, sleeping, sanitary arrangements, food and water, have to be considered; so this should be done in a patrol harbour, away from the site chosen for the ambush. Ambush patrols will almost always have to be self-sufficient, as re-supply would not be possible without compromising their position.
