Tank
With World War II the multi-turreted tanks proved impracticable, and as the single turret on a low hull design became standard, crews became standardized around a crew of four or five. In those tanks with a fifth crew member, usually three were located in the turret (as described above) while the fifth was most often seated in the hull next to the driver, and operated the hull machine gun in addition to acting as a co-driver or radio operator. Well-designed crew stations, giving proper considerations to comfort and ergonomics, are an important factor in the combat effectiveness of a tank, as it limits fatigue and speeds up individual actions.
Hezbollah armed strength
Hezbollah's anti-armor capabilities consist of ATGM teams with 5 or 6 fighters. The typical team had two highly trained operators, within Hezbollah called "tank snipers" or "Mirkava fighters," and two or three porters to move the heavy missiles. Fighters are trained in anti-tank weapons, ambushes, and camouflage. Hezbollah apparently stole a combat simulator from Fouad Shehab Command and Staff College and uses it to train anti-tank teams. Reportedly, in the 2006 war, Hezbollah's most skilled anti-tank teams were held back in reserve in expectation of a major Israeli attack and did not see combat. One of Hezbollah's common tactics was to wait under cover for an Israeli vehicle to pass by, then attack from the rear, where the armor is weakest. Fighters swarm Israeli tanks with dozens of cheap ATGMs to strip off reactive armor and active protection systems, then use a powerful missile like a Kornet, Toophan or RPG-29 to destroy the tank. ATGM teams also target individual soldiers and occupied buildings with missiles. They operate alongside infantry as part of combined arms. To avoid airstrikes and counter-fire, the teams rely heavily on mobility. Since 2006, Hezbollah seems to have made more of an effort to use recoilless rifles and cheap ATGMs in their swarming mix.
