Peninsula Shield Force is a military arm of

The Peninsula Shield Force (PSF) is the joint military arm of the Gulf Cooperation Council (GCC), a regional political and economic alliance comprising Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates. Established in 1984 (following a 1982 agreement), the force is headquartered at the King Khalid Military City in Saudi Arabia and is tasked with the collective defense of the GCC member states [1]. The PSF consists of infantry, armor, and artillery units contributed by all six member nations. Its most notable deployment occurred in March 2011, when it was sent to Bahrain at the request of the Bahraini government to maintain security during civil unrest [1]. While the GCC focuses on economic integration, the PSF represents its primary mechanism for security coordination and regional military deterrence.
