Page "Ambush" Paragraph 3

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.
