Against this atgm would be alot more better one or two would do the trick
Most modern atgm's have shaped charges(shaped charges, often used in anti-tank warfare, utilize a carefully designed cavity (often conical) within the explosive to focus its energy into a high-velocity jet of molten metal. This jet, formed by the detonation of the explosive and the collapse of the liner (a metal lining within the cavity), is what penetrates armor. While the jet's kinetic energy is the primary cause of penetration, the heat generated during this process can also contribute to incendiary effects after penetration).
this turtle shell will make atgm explode before it comes in contact with tank armour, a layer of air between the exploding charge and tank armour will be there.
Spaced Armor vs. Shaped Charges
Spaced armor refers to armor arranged in layers with gaps (air or other material) in between.
Why spaced armor helps:
Jet disruption: The jet formed by a shaped charge begins to break up and decelerate as it passes through air or light materials (like rubber, foam, or even thin steel plates).
Detonation standoff control: HEAT rounds have an optimal standoff distance (~1–3 charge diameters). If they hit something before the optimal point (like a spaced plate), the jet forms too early and loses effectiveness.
Pre-detonation: Outer layers can trigger premature detonation, so the jet is poorly focused by the time it reaches the main armor.
Example:
A shaped charge meant to penetrate 800 mm RHA might only do 300–400 mm if it hits a spaced armor layer 30–50 cm in front of the main armor.
So it's effective against atgm's too, though atgm's will still damage the tank significantly even if it couldn't penetrate the armour.
