ATGM

Early Cold War: first generation ATGMs

First-generation ATGMs use a type of command guidance termed manual command to line of sight (MCLOS). This requires continuous input from an operator using a joystick or similar control system to steer the missile to a target. One disadvantage of this is that an operator must keep the sight's reticle cross hairs on a target and then steer the missile into the cross hairs, i.e., the line-of-sight. To do this, an operator must be well trained (spending many hours on a simulator) and must remain stationary and in view of a target during the flight time of the missile. Because of this, the operator is vulnerable while guiding the missile. In addition to the low kill probability, other problems with first generation ATGMs include slow missile speed, high minimum effective range, and an inability to use top attack missiles.
