Who is fighting in Yemen

""Most regular troops employed by the Saudi coalition in Yemen are also foreigners, according to reports. In 2015, officials in Yemen's government claimed that Egypt had sent ground troops to fight alongside government forces, while earlier this year senior security forces told MEE that the Pakistan army sent a brigade of combat troops to shore up Saudi Arabia's vulnerable southern border from reprisal attacks mounted by the Houthis. The UAE, which is part of the Saudi coalition, was revealed by the New York Times to have recruited hundreds of Colombian, Panamanian, Salvadoran and Chilean mercenaries to do their dirty work in Yemen. “Mercenaries are an attractive option for rich countries who wish to wage war yet whose citizens may not want to fight,” said Sean McFate, a senior fellow at the Atlantic Council and author of The Modern Mercenary.""
