Really Funny, Yer Highnesses.
In case you're truly not familiar with EMT-ST, it was derived years & years ago from the Golden Hour principle. It is accepted within the medical community that R. Adams Cowley, MD, the "father" of Shock Trauma, & the Golden Hour principle, saw the need for specialized care at trauma incidents, & at hospitals receiving the trauma patients. Here's the link to University of Maryland, where it explains it all.

Virginia developed EMT-ST primarily, I believe, for rural EMS providers, (who where not "able", for whatever reason, to obtain their Paramedic education, ) in order to effectively treat trauma patients, when your closest trauma center (or closest facility cable of stabilizing a patient) is 45 mins - an hour away. Regardless, ST is being phased out currently, and I believe it's almost totally gone.
