Like other Spike missiles (Spike -SR, Spike -MR, Spike -LR, Spike -ER missiles), Mini-Spike is the active seeker of voltage coupled device (CCD) or infrared imaging (IIR). However, the signal transmission is wireless, and other spike missiles (except Spike -SR) are all optical fiber transmission. A system includes command and launch unit (CLU) and barrel-mounted missiles (all missiles are barrel-mounted and easy to carry). The command launch unit (CLU) weighs 4 kg, and the barrel missile weighs 4 kg. When the soldiers fired, the total weight was 8 kilograms. According to the standard configuration of Israeli infantry, an infantry should carry 12kg missile equipment, including launch unit (CLU), barrel-mounted missiles or three barrel-mounted missiles. The range of "mini spike" has reached 1200m. There are two ways to launch a missile: ignore it after launch and observe and correct it after launch. Before launching, it can be set to approach the target at low, medium and high angles of attack. What's more, after you launch the missile, you can order the warhead of the missile to be disabled, so that the missile can only use kinetic energy to attack the target to reduce collateral damage.
Due to the advanced guidance method, spikes can easily attack enemy buildings, machine gun positions, armored vehicles and tanks. Although compared with other anti-tank missiles, "mini spike" has problems in dealing with the front armor of the tank because of its smaller warhead, it can attack the target at a high angle of attack by setting "mini spike" before launching, thus attacking the top of the tank. Although the front armor of the tank is very resistant, the top is still very weak.
