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:
“This teaching is not practical in the sense in which the New Testament is. It is not always sound sense in practice. The Brahman never proposes courageously to assault evil, but patiently to starve it out. His active faculties are paralyzed by the idea of caste, of impassable limits of destiny and the tyranny of time.”
—Henry David Thoreau (1817–1862)
“Without infringing on the liberty we so much boast, might we not ask our professional Mayor to call upon the smokers, have them register their names in each ward, and then appoint certain thoroughfares in the city for their use, that those who feel no need of this envelopment of curling vapor, to insure protection may be relieved from a nuisance as disgusting to the olfactories as it is prejudicial to the lungs.”
—Harriot K. Hunt (1805–1875)
“The individual protests against the world, but he doesn’t get beyond protest, he is just a single protester. When he wants to be more than that, he has to counter power with power, he has to oppose the system with another system.”
—Friedrich Dürrenmatt (1921–1990)
