From The Big Picture episode TV-696, "Your Army Reports" #7.
Originally a public domain film from the National Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied.
The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).

The M118 Demolition Charge is an easy-to-use block of adhesive-backed sheet explosive that can be cut to any shape or dimension and quickly applied to flat, curved or irregular surfaces allowing for tailored application for a variety of targets...
When it comes to breaching targets, explosive demolition and Improvised Explosive Detonation, EBAD's M118 Demolition Charge, useable in a variety of environments including underwater, is an obvious answer. Comprised of 2 ½ pound sheets of PETN based flexible explosives in mylar wrapper, EBAD's M118 Demolition Charge is designed for cutting, especially against steel targets. Each explosive sheet, measuring 12” long by 3” wide by ¼” thick, has a pressure sensitive adhesive attached to one surface and a vapor tagging agent which makes them easily detectable. All M118 Demolition Charges are qualified and tested to MIL-PRF-46676. They are manufactured, inspected and tested IAW MIL-C-50850 and NSN 1375-01-399-3718 DODIC M024.

Pentaerythritol tetranitrate (PETN), also known as PENT, PENTA, TEN, corpent, or penthrite (or, rarely and primarily in German, as nitropenta), is an explosive material. It is the nitrate ester of pentaerythritol, and is structurally very similar to nitroglycerin. Penta refers to the five carbon atoms of the neopentane skeleton. PETN is a powerful explosive material with a relative effectiveness factor of 1.66. When mixed with a plasticizer, PETN forms a plastic explosive. Along with RDX it is the main ingredient of Semtex...
