squad falls into three broad categories: classical, balanced and combined.

Classical

'classical' squads are composed of three elements; a command and support element, a base of fire element, and a maneuver element. The command and support element could include a squad leader, an assistant squad leader, a medic, a forward observer and a radio operator or it could be limited to a squad leader. The fire element consists of a machine gunner and one or two personnel who act as loaders and barrel changers for the gun and porters for its ammunition and ancillary components. The maneuver element is composed of troops armed with

Combat Strategy and Phases

Assault

The two major techniques of squad assault are bounded fire and advancing under the cover of suppressive fire of supporting units. Bounded fire entails having one element of the squad provide covering fire and field obscuration while the second element maneuvers forward to provide covering fire that allows the first element to leapfrog forward. This process is repeated until the maneuver element is in grenade range of the enemy positions. Advancing under the cover of supporting units requires the squad to stealthily advance towards the enemy position from a weakly held sector after the enemy has been suppressed by overwhelming fire. Once the squad has closed with the enemy it uses grenades and squad automatic fire to engage the enemy. This allows sufficient disruption of the enemy's control of their defensive front to allow other squads to advance unopposed.

will be examined to replace damaged ceramic plates. Casualties will be treated, evacuated and/or replaced. The squad will use this period to familiarise itself with its surroundings, dig in to defensible positions, recharge itself, repair any damage to itself and prepare either for the next offensive movement, or go on the defensive against a counterattack.

Defensive

On the defensive, an isolated squad will allow a small element to hold a weak and easily evacuated position behind a remote detonated mine, flanked by a machine gun. As the enemy advances, the small forward element will pull back. When its former position is overrun the mine will be detonated to distract the attackers, and then the machine gun will open fire on the attacker's flank. The machine gun will then switch to engage and suppress the tail of the enemy assault as the rest of the squad maneuvers against its dislocated and exposed flanks, which have been pulled forward from their defensive line to support the head of the assault. On the defensive, a squad with a secure means of communication will fix the enemy into interlocked fields of fire and call in fire support from supporting units.
