On 28 March, a 7.7-magnitude earthquake near Mandalay shook Bangkok, collapsing a 33-story building under construction and killing at least 92 people. At Thailand’s request, over 100 U.S. Army, Marine, Air Force, and Navy personnel deployed from 28 March–4 April to assist in search and rescue, with special units such as the 353rd Special Operations Wing and 31st Rescue Squadron working alongside Thai forces under JUSMAGTHAI coordination.
