A little digging. Air defense was recently installed at Mar-A-Lago. In late October, the US military (NORAD/USNORTHCOM) deployed AN/TWQ-1 Avenger short-range air defense systems (Humvee-th Stinger missiles) plus anti-drone capabilities at Mar-a-Lago (including on the Bragg in Lake Worth) and at nearby Trump International Airport. It was at the request of the Secret Service.
