(CNN) As Saudi Arabia, along with a growing list of other countries, cut diplomatic ties with Qatar on Monday, it called on its allies to cease all travel and transport with its neighbor.

One of Saudi Arabia biggest allies, however, is the United States, which also happens to maintain its biggest concentration of military personnel in the Middle East at Qatar's Al Udeid Air Base.

The sprawling base 20 miles southwest of the Qatari capital of Doha is home to some 11,000 US military personnel.

The US Combined Air Operations Center (CAOC) at Al Udeid Air Base, Qatar, provides command and control of air power throughout Iraq, Syria, Afghanistan, and 17 other nations.

The base, which boasts one of the longest runways in the Persian Gulf at 12,500 feet, is a strategically important facility that can accommodate up to 120 aircraft.

In 2016, the base was used as staging ground to fly B-52 airstrikes against ISIS targets in Iraq and Syria. Early in the Afghanistan campaign , F-16 fighters and E-8C Joint Stars reconnaissance planes that monitor ground units were based there, along with refueling tankers.
