What is non-explosive reactive armor?

• A. Explodes outward to cancel projectile effects.
• B. Cancels projectile effects using a secondary outward explosion.
• C. It is armor that detects infrared radiation.
• D. It serves as a filler between armor plates, allowing outer plates to cave in and absorb impact.

Answer: (D)

Non-explosive reactive armor works by placing a deformable, energy-absorbing filler between armor plates. When a shaped-charge jet or high-velocity impact hits the outer plate, the filler and plates respond in a way that causes the plates to cave in and the jet to deform or fragment, spreading the energy over a larger area and reducing penetration. There’s no explosive detonation involved, so the protection comes from mechanical disruption and energy absorption rather than a blast or counter-explosion. This is why the idea of a filler between plates that allows the outer plates to cave in and absorb the impact best describes non-explosive reactive armor.
