M83 Pincer Grenade (heavy canister charge arrayed anti-tank mine)

"Then it came into full view- a blast-scarred chrome Leviathan on treads.  The huge under-slung turret guns pivoted in their arc, pounding the surrounding ruins into flat rubble.

Reese un-strapped a satchel from Ferro's back and quickly pulled out one of the cylindrical anti-tank mines and laid it on his knee.  Ferro followed Reese's lead.  They could hear the H-K swinging on its axis and coming closer.

Remove the dust plug.  Reese steadied his breathing.  Test the circuit.  The huge monster was coming into range.  Disengage the safety ball.  Reese's hands were sweating, slipping against the stainless-steel casing.  Grasp the handle and twist, clockwise, from SAFE to ARMED.  The ring around the top half of the mine lit up.  it was hungry.

Reese peered over the edge of the wall.  The H-K was only a few yards to the front, the roar of its engines building to a fever pitch.  He stared into the treads, locked his eyes on them.

Now die, motherfucker!

He leaped up and straight-armed the mine into the Leviathan's path.  One of its treads rolled right over the bomb.  The monster paused, guns and searchlights swiveled.  The head turned, ponderously."

-Frakes and Wisher, "The Terminator"

Sgt. Reese and Cpl. Ferro, the last surviving member of Reese's twelve-man
squad, prepare to take out a heavy tracked HK with their M83 canister charges.

The M83 utilized an advanced binary stabilized liquid explosive (BINASLEX) device combining two inherently stable liquid high explosive mediums, stored under high pressure, into a single volatile solution. The device measured half a meter in length and a quarter meter in diameter, weighing exactly 5 kilos. A web harness constructed of nylon allowed a soldier to carry two of the M83HCCs slung over their shoulder in a quick release mount.  If more than this number were carried, the extra units quickly became clumsy and cumbersome to wield or carry, especially in confined spaces among the debris fields or if the soldier was actively being pursued.

byproduct of the two inert binary elements becoming a radical solitary element.

The M83HCC was called a "pincer" grenade because of its arming sequence and the fact that most of the M83HCCs were thrown rather than placed as an anti-armor device. The activation of the M83HCC involved a "pincer" action which forced two inert binary elements together to form a radical solitary element that rapidly built in chemical explosive power, a mixture where the whole was greater than the sum of the parts, by several factors. 

The M83HCCs arming sequence is designed to be simple and straight-forward; a large handle on the top of the canister is pulled 5cm upward and twisted 180 degrees in a clockwise rotation to afford a 10 second mixture rate of the two binary explosive liquids. Twisting the handle ten degrees further allows more time in mixing, in 5 second increments, up to a full minute. Notches on the rim of the arming cap allow the user to dial-in the correct arming time sequence using the arming handle, even if by feel alone. Pulling and turning the handle arms the M83 HCC by directing the two liquid explosives to flow from separate holding tubes into a central mixing chamber. A warning light on the rim of the HCC glows bright green and then slowly grows dim as the mixture is completed. Detonation is by a high amperage electric current directed into the central mixing tank as soon as both holding tubes are empty and the central tank reads full.  The detonating current is supplied by an integral battery which may be kept charged by a special rack which holds the M83HCCs.  The battery has a shelf life of 5 years without recharging.  M83HCCs with depleted batteries may be charged and used successfully even after years of being uncharged, as long as the internal battery has not been damaged or become corroded.  Replacement batteries are available in most armorer's kits.

The two liquids, though stable in each separate holding tank, become electrically volatile when mixed. A full 4 kilos of liquid high explosive is produced (2 kilos of each material, LiqEx A and LiqEx B) in the central mixing chamber. Each kilo of BINASLEX, when properly mixed, is the equivalent of 5 kilos of C-4 plastique. The M83HCC was a common demolition device used by the military during the last War.  it was usually placed against a structure that was to be demolished and then activated for maximum fusing, allowing the human operator a wide margin of safety in order to clear the blast radius.  A special cone-shaped filter could be attached to the device to tamp the charge and direct the energy of the explosive into a shaped ("Monroe") effect suitable for demolition work.  These cone filters were comparatively rare but did see use in the final offensive against SKYNET at the Cheyenne Mountain complex in 2029 A.D.

During the War, the humans found that the M83 was well suited for cracking the heavy armor of SKYNET's larger ground units.  A well placed charge, often thrown at the last second from protective cover, could penetrate the hyperalloy armor belt which were less thick on the underbody, the compression wave being capable of cracking the hyperalloy combat case where it was thinnest, allowing the high velocity plasma jet to enter the fighting body and wreck the internal components, often setting up sympathetic internal explosions and wrecking the larger units.  Feedback damage from the initial explosion, as well as shrapnel and fragmentation in the form of anything the explosion can sweep up off the ground, can be lethal to the user if the user is not properly shielded or has not taken cover. Other Resistance units have installed trip wires, remote laser communicator detonators and even pressure switches to already pre-armed M83HCC units in order to produce effective ambush traps in advance of known Machine patrol routes.
