The Pentagon has confirmed it is sending a high-altitude anti-missile system operated by US troops to Israel. Officials say the Terminal High-Altitude Area Defense (Thaad) battery will bolster Israeli air defences after Iran’s missile attack on the country earlier this month.

The THAAD defense system is one of the US military’s most powerful anti-missile weapons, capable of intercepting ballistic missiles at ranges of 150 to 200 kilometers (93 to 124 miles) and with a near-perfect success rate in testing.

U.S. Army leaders say the deployment of a Terminal High Altitude Area Defense battery to Israel and roughly 100 soldiers to operate it will add to strains on the Army’s air defense forces
