Tank
Most modern tanks most often have four crew members, or three if an auto-loader is installed. These are the:
Historically, crews have varied from just two members to a dozen. For example, pre-World War II French tanks were noted for having a two-man crew, in which the overworked commander had to load and fire the gun in addition to commanding the tank. First World War tanks were developed with immature technologies; in addition to the crew needed to man the multiple guns and machine guns, up to four crewmen were needed to drive the tank: the driver, acting as the vehicle commander and manning the brakes, drove via orders to his gears-men; a co-driver operated the gearbox and throttle; and two gears-men, one on each track, steered by setting one side or the other to idle, allowing the track on the other side to slew the tank to one side.
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.
