Editing MBT-70 (section)

===Protection===
The frontal area of both the hull and turret was protected by spaced armor and provision was made for the installation of a [[polyethylene]] radiation shielding to achieve an attenuation ratio of 20:1 against [[neutron radiation]].

The outer layer was made of High Performance Armour developed in the United States and incorporated in the mid-1960s in the design of the MBT-70.<ref>{{Cite book|title=Technology of Tanks (Vols 1-2)|last=Ogorkiewicz|first=Richard M.|publisher=Janes Information Group|year=1991|isbn=978-0710605955|location=London|pages=361}}</ref> The High Performance Armour contained 9% of [[nickel]] and 4% of [[cobalt]] and was produced by [[vacuum arc remelting]]. It was heat treated to 500 BHN, like the other types of high hardness armor, but it was produced from the start in the form of plates 40&nbsp;mm thick. The armor was well protected against gun fired HEAT munitions, but lacked protection against kinetic munitions. 

Two watertight armored transverse bulkheads separated the crew in the center from the multi-ply rubber fuel tank in the front compartment and the engine compartment in the rear.

To save weight, aluminum was used for the engine compartment floor and for access doors on the engine deck.
The MBT-70 was protected against [[electromagnetic pulse]]s and [[NBC (weapon)|nuclear, biological and chemical weapons]] as well.

The tank's low silhouette, which could be lowered from {{convert|2.59|m}} to only {{convert|1.99|m}}, was also a large advantage. Compared to the M60 tank, the MBT-70 had a lower profile. With the hydropneumatic suspension lowered it was also smaller than the Leopard 1, which gave the MBT-70 a better [[hull down]] position.{{Citation needed|date=February 2013}}

The MBT-70 was equipped with eight XM176 [[smoke grenade|smoke]] [[grenade discharger]]s, each discharger barrel contained two smoke grenades; one [[AN-M8 smoke grenade|AN-M8 HC]] and one [[M34 grenade|M34 WP]].{{sfn|Hunnicutt|1990|p=134}} Actuated from the commander's station, these launchers provided close-in protection and concealment for the vehicle. The KPz-70 was equipped with 16 in four rows of 4.
