The ISC-2 Infantry Support Cannon, is a weapon straight from the archives found under Desert Star. The U.S. Army devised an infantry support weapon in the late 2080s, that utilized the concept of rail gun technology, in a rifle version of a small caliber cannon. The first step was developing a special ammunition that could be used with such a weapon. They began with the basic design of a new age explosives, 20 mm Armor Piercing, cannon shell. They then added metal rings around the tip, mid way, and base of the cannon shell itself. This allowed it to be fired conventionally, giving it a rapid velocity at the ignition of the powder in the shell casing, and then further accelerating the round with an electromagnetic accelleration coil at the base of the barrel. This resulted in a much greater penetration value than the 20 mm cannon shell fired normally would allow.
S-Mart was very quick in developing electromagnetic technology, because of it's practical applications in so many different fields. At first, the basic support weapon of choice was the S-Mart RFFC-17, but because of it's heavy weight, and small payload of shells permitted by the magazine design, the ISC-2 was produced to supplement it in the role of infantry support. The first examples of which reached N.O.M.A.D. service in early 114PA.
The ISC-2 has become notorious in Western North America for several of it's traits. It has attained a bad reputation for having a horrendous kick - despite the efforts of it's designers to include a series of shock absorbing segments to the weapon, two in the stock of the weapon, and a large one along the barrel intended to absorb the majority of the recoil. It's nickname given by unfamiliar users of the type, because of these efforts, is rather unglorifying. The two most frequenty used names are "Bionic Mule" and "Boom-Spring". Despite this it is still quite popular because of it's capabilities as a good infantry support weapon. The ISC-2 is still produced in batches of 100-300 to retain a satisfactory number in N.O.M.A.D. service, as well as for commercial value, selling them frequently to mercenary companies, and independent buyers alike.
