1 The new Air Optix Night and Day Approximately 4 months ago, I was having problems with my new set of Night and Day lenses, called the Air Optix Night and Day Aqua which replaced the former Focus Night and Day. 2  Upon some research on the Internet, I found that I was not the only one experiencing problems.
(Redirected from Short Range Air Defense) Short Range Air Defense (SHORAD) is a group of anti-aircraft weapons and tactics that have to do with defense against low-altitude air threats, primarily helicopters and low-flying close air support aircraft such as the A-10 or Sukhoi Su-25.
The Avenger has also been deployed during the U.S. military's operations in Afghanistan and Iraq. In 2004, the U.S. Army had 26 battalions with Avenger Short-Range Air Defense (SHORAD) capabilities, but prioritization of other weapon systems during operations in Afghanistan and Iraq caused that number to drop to nine by early 2017, of which two were within the active force and seven were in the Army National Guard.
