The M112 demolition blocks of C-4 are commonly manufactured into the M183 "demolition charge assembly",<ref name=M15 /> which consists of 16 M112 block demolition charges and four priming assemblies packaged inside military Carrying Case M85. The M183 is used to breach obstacles or demolish large structures where larger [[satchel charge]]s are required. Each priming assembly includes a {{convert|5|or|20|ft|m|adj=on|spell=in}} length of detonating cord assembled with detonating cord clips and capped at each end with a booster. When the charge is detonated, the explosive is converted into compressed gas. The gas exerts pressure in the form of a shock wave, which demolishes the target by cutting, breaching, or cratering.<ref name="global" />
