Typical strawman. The $84 million for erectile dysfunction drugs (which work for PTSD...the erectile part was a happy side effect of the drug), was divided between hundreds of thousands of active, retired military and their dependents. Like the rail, the initial costs of a transgender surgery are extremely high in cost, but is dwarfed by the constant and life long maintenance and upkeep treatments necessary for the patient. 
Or, as is typical with SJWs, are you going to cut off their aid after you've used them and they aren't needed by you guys anymore?
