Which type of breach involves the use of explosives?

The type of breach that involves the use of explosives is the explosive breach. This method is specifically designed to quickly and effectively penetrate barriers, such as doors, walls, or other structures, by employing explosive charges. The explosive breach is utilized in situations where immediate entry is required, or where other methods are insufficient for overcoming obstacles.

In terms of context, mechanical breaches involve using tools and manual force to gain entry without explosives, while ballistic breaches utilize firearms to create openings; these techniques do not rely on explosive charges. Structural breaches, on the other hand, usually focus on compromising the integrity of a structure through non-explosive means, potentially involving mechanical or manual approaches. Thus, the explosive breach stands out as a method that specifically incorporates explosives to create an entry point.
