Direct proof of use
BAE Caiman MRAPs were documented in the 2014 Yemen Civil War with southern secessionist forces supported by the United Arab Emirates. Written evidence submitted to the UK Parliament by Arab Reporters for Investigative Journalists said the vehicles were used by Security Belt, Hadrami Elite, Shabwani Elite, and Southern Giants forces, and specifically placed Caimans in the fighting inside Hodeidah port.
CNN-linked reporting from October 2019 added a separate incident-level claim: local journalists filmed U.S.-made MRAPs used by Southern Transitional Council-led separatist militias, including a BAE Caiman used in fighting for Shabwah against government forces in August 2019.

Timeline
In September 2014, the U.S. Defense Security Cooperation Agency notified Congress of a proposed UAE purchase covering refurbishment and modification of 4,569 MRAP vehicles from U.S. Army stock, including 1,150 Caiman Multi-Terrain Vehicles. The notice described the package as Excess Defense Articles and named BAE Systems in Sealy, Texas, among the principal contractors.
By 2018-2019, open-source and investigative reporting placed BAE Caimans in Yemeni service with UAE-backed southern formations. The ARIJ parliamentary submission identified use by Southern Giants forces in the Hodeidah port fighting, while CNN-linked reporting identified a BAE Caiman in separatist fighting in Shabwah in August 2019.

Narrative
The Caiman evidence in Yemen points to a protected-mobility role rather than a single fixed weapons role. The vehicles were reported with UAE-backed southern forces, where MRAP protection was relevant to convoy movement, troop transport, urban fighting, and front-line movement in areas such as Aden, Shabwah, and Hodeidah.
The transfer context is separate from battlefield use. The 2014 U.S. sale notification documents the UAE request for Caiman MTVs and other MRAPs, but it does not itself prove Yemen deployment. The Yemen-use claims come from later investigations that identified Caimans with southern secessionist and Southern Giants forces during the war.
The strongest available public evidence names southern forces and locations, but it does not establish a full vehicle-by-vehicle chain of custody. The record therefore treats the Caiman as fielded by UAE-backed southern forces and STC-linked separatists in the Yemen conflict, with the UAE acquisition as background for how Caiman MTVs entered the regional inventory.
