How much armor is on an MBT?

• A. Up to 500mm
• B. Up to 1,000mm
• C. Up to 750mm
• D. Up to 2,000mm

Answer: (B)

Main battle tanks use very heavy armor, especially on the front of the hull and the turret. The protective layers are not just solid steel; they’re advanced composites and spacing that boost protection in terms of a hardened steel equivalent. Because of this, the practical upper bound for front armor typically cited is about 1,000 millimeters in RHA equivalence. That means the thickest, most protected front sections can resemble roughly a meter of steel in how well they resist certain threats. The other numbers would either underestimate the maximum front protection or describe areas that aren’t the primary protection zone; 2,000 mm would overshoot what modern MBTs generally achieve. So the best reflection of how much armor an MBT has is up to about 1,000 mm.
