The Pentagon has confirmed that American forces will be sent to operate an advanced missile defense battery ahead of a likely Israeli attack on Iran.

Pentagon Press Secretary Maj. Gen. Pat Ryder announced on Sunday that the US has ordered the deployment of a Terminal High Altitude Area Defense battery air defense system ( THAAD) to Israel, along with a crew of American service members to operate it.

The move marks the first deployment of US combat troops on Israeli soil since the so called Israel-Hamas war started last year and comes as Iran warned Washington to keep American military forces out of Israel.

RT report: According to Ryder, the THAAD battery “and associated crew of US military personnel” will be stationed in Israel “to help bolster Israel’s air defenses following Iran’s unprecedented attacks against Israel on April 13 and again on October 1.”

US President Joe Biden, who the White House previously said had “no plans or intentions to put US boots on the ground in combat,” ordered the deployment, Ryder stated.

The THAAD, or Terminal High Altitude Area Defense system, is a mobile anti-ballistic missile system designed to detect and intercept ballistic missiles during their descent stage. It fires a non-explosive projectile at eight times the speed of sound, relying on kinetic energy to destroy incoming missiles.

A THAAD battery consists of 95 soldiers and six truck-mounted launchers capable of firing a total of 48 interceptors.

The US deployed a THAAD battery to Saudi Arabia after the Israel-Hamas war began last October, and to Israel on a training exercise in 2019. However, neither the system nor the American troops who operate it have been sent to Israel since the current conflict began.

While American soldiers took part in a brief aid mission off the coast of Gaza earlier this year, they did not set foot in the Palestinian enclave.

The deployment comes as Israel prepares its response to an Iranian missile attack on October 1, in which around 200 ballistic missiles were fired at Israeli military targets. Tehran maintains that the strike was a “legitimate” response to Israel’s assassination of Hamas leader Ismail Haniyeh in Tehran and Hezbollah leader Hassan Nasrallah and a senior Iranian general in Beirut.

Israel is widely expected to target Iran’s oil or nuclear infrastructure, although the US has advised West Jerusalem against either choice. Whatever form the Israeli response takes, Iran has vowed to retaliate. Earlier this week, a source in Tehran told RT that this retaliation would be “proportionate.” Should West Jerusalem target Iran’s oil infrastructure, Tehran will respond by striking Israel’s oil refineries. Attacks on other infrastructure, such as power plants or nuclear facilities, will likewise prompt retaliatory strikes on corresponding installations in Israel, the source explained.

Hours before Ryder’s announcement, Iranian Foreign Minister Seyed Abbas Araghchi warned that the US is putting the “lives of its troops at risk by deploying them to operate US missile systems in Israel.”

“While we have made tremendous efforts in recent days to contain an all-out war in our region, I say it clearly that we have no red lines in defending our people and interests,” Araghchi added.”
