The Egoz unit (621) was established in 1995 and was named after the legendary "Egoz" reconnaissance unit. The unit was established in order to bring about a revolution in terms of the IDF's capabilities in combating the Hezbollah terror organization, and to this day it specializes in guerilla warfare, mainly along the northern border of the country. It is a part of the Commando Brigade.

Egoz specializes in fighting in complex terrains, fieldcraft, camouflage, and in miniature warfare (short-range warfare in which the quality and professionalism of the soldier are the main components which bring them success). The unit operates at any time, in any arena and in every sector, while focusing on northern Israel.

The unit also has a unique weapons division the unit's development company, which is responsible for finding creative solutions and technological innovations for problems that arise in the field, and providing protection against new enemy attacks.
