The development project completed, the Aerojet team sent the project back to Picatinny. When mines are employed in the controlled role, they are treated as individual weapons and are reported in the unit fire plan. This was determined experimentally by Bledsoe, through a large number of test firings. It was caused by two claymore mines placed side by side on the bus by LTTE cadres, which spraying the packed bus with millions of ball bearings upon manual detonation. Optimum range is 50 to 100 meters. In total the mine weighed about 2.43-pound (1.10 kg), and could be fitted with an optional peep sight for aiming. The mine can be detonated by any mechanism that activates the blasting cap.

[1] Originally an aluminum box was used to hold the generator. They were awarded a $375,000 development contract to improve the Claymore design. The M18 is a command detonated mine that is directional. The M18 was 9.25-inch (235 mm) long and 3.27-inch (83 mm) high, held in a plastic case with three folding spike legs on the bottom.

Its lethality out to 50 metres arrives in the form of 650 steel balls and it is activated by remote control or trip wire. M18 Claymore The M18 Claymore, a directional fragmentation mine, is 8-1/2 inches long, 1-3/8 inches wide, 3-1/4 inches high, and weighs 3-1/2 pounds. Detonation is initiated by a No 2 electric blasting cap. This was found to be undesirable for a number of reasons. A layer of tinfoil was added between the fragmentation matrix and the explosive. Type of Directional fragmentation anti-personnel mine. In early 2015, the U.S. Army began testing a smaller version of the Claymore called the Mini-Multi-Purpose Infantry Munition (M-MPIMS). It weighs 2 lb (0.91 kg) and has a 50 m (160 ft) effective range, similar to the full-size Claymore. Testing concluded that the mine was effective out to approximately 110 yards (100 m), being capable of hitting 10% of the attacking force. The force of the explosion deforms the relatively soft steel balls into a shape similar to a .22 rimfire projectile. The M18A1 Claymore is a directional anti-personnel mine developed for the United States Armed Forces. The steel balls are projected in a 60° fan-shaped pattern that is 6.5 feet (2.0 m) high and 50 m (55 yd) wide at a range of 50 m (55 yd). The M18a1 claymore mine is based around a 1.5lb slab of plastic explosives packed behind 700 steel balls. A simple open sight on the top surface allows for aiming the mine.

There are field-expedient methods of detonating the mine by tripwire, or by a timer, but these are rarely used. In comparison, the other anti-personnel weapons of the Vietnam War available to the US Army was the M67 fragmentation hand grenade, this having a kill-zone of up to 16.5 feet (though lobbed distance was limited to the thrower's arm ability), and the M79 single-shot grenade launcher, a pinpointed weapon sending a 40mm high-explosive (HE) grenade upwards of 1,149 feet down range - though these were similarly limited with a kill range of about 20 feet. An electrical blasting cap for triggering the mine was inserted through a small hole in the side. A number of licensed and unlicensed copies of the mine have been produced. The M18A1 Claymore mine has a horizontally convex green plastic case (inert training versions are blue). [7] Given the requirements of weight and fragment density, approximately 700 fragments were needed, with the ability to aim the mine with an accuracy of around two feet (0.61 m) at the center of the target zone. The M68 kit is designed to familiarize personnel with the placement and arming of a real M18 directional mine.
