While this gives the tank a lower profile so it can better avoid getting hit by enemy tanks, the tradeoff is being extremely vulnerable once hit (even an indirect hit) which will likely set off the ammunition stored in a ring along the inside of the turret right next to the crew. Some modern tanks such as the Russian T-72, T-80, and T-90, feature a compact three-crew design with an auto-loading mechanism, eliminated the need for a fourth crew member who is the loader.

The jack-in-the-box effect is only known to occur in tanks which are "buttoned up" (i.e. This causes a massive and instantaneous overpressure in the sealed internal compartment of the tank, until it explodes outwards through the weakest point in the otherwise homogeneous compartment, namely the turret ring, blowing the turret completely off the chassis and into the air in a gout of flame. If an anti-tank projectile or shaped-charge blast manages to penetrate a turreted armored vehicle's hull and subsequently its ammunition storage area, the shock wave or heat and pressure can be sufficient to cause cooking off or sympathetic detonation of some or all of the tank's unfired explosive shells and propellant. Most of the time the crew inside does not survive. It is named after the child's toy, the jack-in-the-box, in which a puppet pops up. The jack-in-the-box effect is a specific effect of a catastrophic kill on a tank or other turreted armored vehicle in which an ammunition explosion causes the tank's turret to be violently blown off the chassis and into the air.
