US Forces Poised For Iraq Response-USS George H.W. Bush carrier strike group

US warships,aircraft and troops are poised for orders to respond to the advance of Iraqi Islamist militants toward Baghdad.In the Persian Gulf,aka Arabian Gulf,are the aircraft carrier George H.W. Bush(CVN 77) and its strike group:guided missile cruiser USS Philippine Sea(CG 58) and guided missile destroyer USS Truxtun(DDG 103),as well as one or more attack submarines.
The George H W Bush has about 60 aircraft to coordinate and execute any strike mission against the militants the President may order.The cruiser and destroyer can launch Tomahawk cruise missiles for precision strike,as can attack submarines.
Also in the Persian Gulf is the amphibious transport dock ship USS Mesa Verde(LPD 19) with 550 US Marines aboard.The Marines are on standby to evacuate up to 5,000 American civilians currently in Iraq.In Iraq itself,170 Marines and Army troops have been added to the permanent US embassy guard force to bolster security and support for US personnel.The Baghdad embassy compound,located in the International Zone,aka Green Zone,is the largest in the world.The Green Zone is a heavily guarded,closed-off area of central Baghdad that houses Iraqi government buildings;private military contractors;and the US,British,Australian and Egyptian embassies.
Another 100 US troops have arrived in the region and are on standby for airfield management,security and logisitics support.
The White House is also considering sending up to 100 special forces troops to Iraq.They would be non-operational,soley for training and advising the Iraqi army on military bases,although authorised to defend themselves.
The main militant group is formally known as the Islamic State of Iraq and the Levant,or ISIL,and has captured extensive territory in both Iraq and Syria.They are only 37 miles North of Baghdad at this writing.
