In Saudi Arabia, Saudi Arabia's security concerns include border security, cyberattacks, instability and Houthi (Ansarallah) rebels in Yemen, international terrorism, maritime security, and regional rivals such as Iran and Turkey

Saudi Arabia has close security ties with the US; the SAAF conducts bilateral exercises with the US military and hosts US forces; the US has participated in a cooperative program to equip and train the SANG since 1973, and much of the equipment for both the regular forces and the SANG has been acquired from the US; Saudi Arabia also has defense relationships with China, France, India, Pakistan, the UK, and fellow Gulf Cooperation Council (GCC) members; it is a member of the Peninsula Shield Forces, a joint military force established by the GCC countries with the aim of maintaining security and stability in the region; the force was established in 1982, and its leadership is based in Saudi Arabia

in 2015, Saudi Arabia led a military intervention into Yemen by a coalition of Arab states in support of the Republic of Yemen Government against the separatist Houthis (Ansarallah); Saudi forces from both the Ministry of Defense and the SANG participated in combat operations in Yemen; Saudi Arabia also raised and equipped paramilitary/militia security forces in Yemen--based largely on tribal or regional affiliation--to deploy along the Saudi-Yemen border (2025)
