Abd Rabbuh Mansur Hadi
The United States picked a proxy force (in this case, tribes allied with government leader Abd Rabbuh Mansur Hadi), armed and trained them, and used them as a ground force against Al-Qaeda factions in exchange for US aid to the regime, totaling more than $600 million. The United States also conducted a significant low-tempo air and drone campaign starting in 2009. The US also occasionally launched commando raids inside Yemen and did base some military personnel in and around al-Annad air base in the south of the country.
