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:
“I have ever deemed it fundamental for the United States never to take active part in the quarrels of Europe. Their political interests are entirely distinct from ours. Their mutual jealousies, their balance of power, their complicated alliances, their forms and principles of government, are all foreign to us. They are nations of eternal war.”
—Thomas Jefferson (1743–1826)
“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)
“In the end we beat them with Levi 501 jeans. Seventy-two years of Communist indoctrination and propaganda was drowned out by a three-ounce Sony Walkman. A huge totalitarian system ... has been brought to its knees because nobody wants to wear Bulgarian shoes.... Now they’re lunch, and we’re number one on the planet.”
—P.J. (Patrick Jake)
