What class of bombs is typically used against reinforced concrete structures?

Penetration bombs are specifically designed to effectively target and destroy reinforced concrete structures. These bombs are built with a hardened casing and often utilize a shaped charge to penetrate the dense material before detonating. Their design allows them to focus explosive energy in a way that maximizes the damage to the structure, making them ideal for targeting bunkers, command centers, and other fortified positions.

In contrast, blast bombs are primarily focused on creating a powerful blast wave to inflict damage over a wide area, which may not be as effective against thick, reinforced structures. General purpose bombs can be versatile in application but lack the specialized design that allows penetration bombs to breach sturdy materials effectively. Thermobaric bombs use a different mechanism, relying on a prolonged blast to create a vacuum effect, which is effective against personnel but is not particularly designed for penetrating reinforced concrete compared to penetration bombs.
