the US Army is reflecting about whether to incorporate wing suits into their arsenal to give paratroopers a directed fast access means for HALO intrusions:
This might just be the future for ultrastealthy airborne assault. Aided by extremely precise instruments and a flight computer, the wingman comes in at low level and high speed, before pulling up and dropping gently to the ground at exactly the right spot. It might sound wild, but it would certainly surprise the bad guys.
My bet is they will find a lot of soldiers who just waited for this:
