Yes, they do have explosives strapped to the exterior! It’s called. Explosive reactive armor. Anti-tank weapons most often employ what is called a shaped charge, which is an explosive device that is shaped in a way to focus the blast energy. Think of it like using a magnifying glass to burn paper, focusing the energy in one small area increases the penetrative power of the Anti-tank weapon. To counteract shaped charges, explosive reactive armor is deployed. The explosive reactive armor detonated when hit, and the shock wave disrupts the focused energy of the shaped charge. While yes this obviously causes some minimal damage to the exterior of the tank, it provides far greater protection than not having it. Also, it allows the tanks to be lighter, move faster, and this be harder to hit

You are probably referring to reactive armour => *”Explosive Reactive Amour” packages*. This special type of armour, often in the form of explosive packages on the outside of the actual tank armour, helps against certain types of anti-amour / armour – piercing ammunition.

Basically an AP shell comes in, ERA explodes, explosive shockwaves heavily diminishes the impact of the AP shell, tank is scarred but survives.

As the explosive blast is deflected to the outside, not the inside, the actual damage to the hard armour behind it is comparatively limited, compared to the chance to actually stop an AP shell going through the armour and vaporizing your crew.

Yes they do, ERA, which stands for Explosive Reactive Armor.

The explosion isn’t enough to damage the vehicle itself, and most importantly, the explosion sends two plates of metal flying towards and away from the tank.

The one going away from the tank shatters the projectile if it’s a kinetic weapon (uses raw mass and energy from flying). The one going down constantly puts itself in front of the projectile or jet, incase of a chemical warhead (Uses an explosion to make a penetrator), as it erodes, as that allows it to absorb a significant portion of the penetrative power before it reached the tank’s actual armor.
