In all reality, slingloading is the term for it. Despite what you may have found on google or whatever other places you wannabes search. It was my job for seven years and the only thing anyone ever called it was slingloading. Now I know you must be some super duper military expert who knows everything about every piece of equipment, every tactic, and so on, but I assure you, if you ask anyone who has ever been involved in U.S. Army Aviation, they will tell you that it's called slingloading, period.
