HUTS, as in HUTS count, stands for Hostages, Unknowns, Terrorists, and Shooters.
Most of the mission countries where Seal Team operates in bear no resemblance to their real world counterparts. With the exception of Belgrade, Serbia, Afghanistan and Mexico. For instance, Kinshasha, the capital of DR Congo is portrayed as being near the Savanna when in reality Kinshasha is a leafy coastal city on the Congo River. Congo is nowhere near any savanna. The Congolese geography is mostly forest and rolling plains. The team would've had to travel to rural Kenya or Tanzania before operating in any savanna like geography.
