Main Page | See live article | Alphabetical index MCLOS (short for Manual Command to Line of Sight) is a method for guiding guided missiles. With an MCLOS missile, the operator must track the missile and the target simultaneously and guide the missile to the target. MCLOS is thus hard to use, and today has mostly been replaced by the easier-to-use SACLOS. See also: SACLOS. This article is from Wikipedia.
