Indian Military

Mechanized infantry are infantry equipped with armored personnel carriers (APCs), or infantry fighting vehicles (IFVs) for transport and combat.

The support weapons for mechanized infantry are also provided with motorized transport, or are built directly into combat vehicles, in order to keep pace with the mechanized infantry in combat. For units equipped with most types of APC or any type of IFV, fire support weapons such as machine guns, autocannons, small-bore direct-fire howitzers, and even anti-tank guided missiles are often mounted directly on the infantry's own transport vehicles.

Compared with "light" (foot-mobile) infantry or motorized infantry, mechanized infantry can maintain rapid tactical movement and (if mounted in IFVs) possess more integral firepower. They require more combat supplies (ammunition and especially fuel) and ordnance supplies (spare vehicle components), and a comparatively larger proportion of their manpower is required to crew and maintain the vehicles.

This is a list of main battle tanks, and other vehicles serving that role, in military service with Indian Army.

The term "main battle tank", in the US, was first generally applied to the US M60 main battle tank in 1960, coinciding with the deactivation of the US Army's last M103 heavy tank battalion, the 2/33rd Armor, and the delivery of the M60 to US units in Europe. The M60, armed with a 105mm main gun, was to be an all purpose tank, armed and protected as a heavy tank, but with the mobility of the medium tank. The MBT would form the backbone of modern ground forces. It is armed and armoured to face as many kinds of threats as possible, but especially direct hits from other tanks and lighter infantry anti-tank weapons. However, the threats to MBTs on a modern battlefield are still numerous.
