An active protection system is a system (usually for a military application) designed to prevent anti-armor line-of-sight weapons from acquiring and/or destroying a target.
Electronic countermeasures that alter the electromagnetic, acoustic or other signature(s) of a target thereby altering the tracking and sensing behavior of an incoming threat (e.g., guided missile) are designated softkill measures.
Measures that physically counterattack an incoming threat thereby destroying/altering its payload/warhead in such a way that the intended effect on the target is severely impeded are designated hardkill measures.

Famous quotes containing the words active, protection and/or system:
“Things happen to us, all the time. It was like that for a century, and it is again. It’s not like here: People always do things, because you are born with it; you are brought up in this spirit, the active approach to life: “Stand up and go.” We were not. We were always passive in our lives.”
—Natasha Dudinska (b. c. 1967)
“Innocence does not find near so much protection as guilt.”
—François, Duc De La Rochefoucauld (1613–1680)
“He is not a true man of science who does not bring some sympathy to his studies, and expect to learn something by behavior as well as by application. It is childish to rest in the discovery of mere coincidences, or of partial and extraneous laws. The study of geometry is a petty and idle exercise of the mind, if it is applied to no larger system than the starry one.”
—Henry David Thoreau (1817–1862)
