Introduction
How is the Military in Yemen and how does it work to maintain Sucity and fight terrorism? In terms of Military and security forces, we have the Yemeni Armed Forces: Yemeni National Army, Air Force and Air Defense, Navy and Coastal Defense Forces, Border Guard, Strategic Reserve Forces (includes Special Forces and Presidential Protection Brigades, which are under the Ministry of Defense but responsible to the president), Popular Committee Forces (aka Popular Resistance Forces; government-backed tribal militia)

Ministry of Interior: Security Forces, Emergency Forces, Counterterrorism Units (2024).
In Yemen, government forces under the Yemeni Ministry of Defense are responsible for territorial defense, but also have internal security functions; their main focus has been the Houthi separatists and protecting Yemen’s maritime borders, which are susceptible to smuggling of arms, fighters, and other material support for the Houthis and terrorist groups operating in Yemen, including al-Qa’ida in the Arabian Peninsula (AQAP) and the Islamic State of Iraq and ash-Sham in Yemen (ISIS-Yemen)

in 2015, a Saudi-led coalition of Arab states (UAE, Qatar, Bahrain, Morocco, Sudan, Kuwait, Jordan and Egypt) intervened militarily in Yemen in support of the Republic of Yemen Government (ROYG) against the separatist Houthis; Saudi military forces conducted operations in Yemen and raised and equipped paramilitary/militia security forces in Yemen based largely on tribal or regional affiliation to deploy along the Saudi-Yemen border; UAE's participation in 2015 included several thousand ground troops, as well as supporting air and naval forces; UAE withdrew its main military force from Yemen in 2019, but has retained a smaller military presence while working with proxies in southern Yemen, most notably the Southern Transitional Council (STC); UAE has recruited, trained, and equipped tens of thousands of Yemeni fighters and formed them into dozens of militia and paramilitary units

in 2022, the RYOG and the Houthis signed a truce, halting military operations and establishing humanitarian measures; the former front lines of conflict, in some areas mirroring Yemen’s pre -unification borders, remain static; AQAP and ISIS-Yemen have remained active in remote areas  (2024)
