Which explosive is used to clear a 90-meter long path?

The Mk59 Linear Demolition Charge is designed specifically for applications such as creating pathways through obstacles, including minefields or debris. This type of explosive system provides a controlled line charge that can clear an area efficiently, making it suitable for a 90-meter long path. Its design allows for a safe and effective method of demolishing obstacles over long distances, which is essential in military operations where precision and effectiveness are critical.

In contrast, the other options serve different purposes within demolition and explosives applications. The M81 Fuse Ignitor is primarily a component used to ignite explosives rather than a demolition tool. The M6 Electric Blasting Cap and the M7 Non-Electric Blasting Cap are used to initiate explosions, but they do not provide the same capability to clear a defined path as the Mk59 does. The Mk59 stands out as specifically tailored for linear demolition tasks.
