Military skydiving is done by special forces teams, such as Navy SEALS
or Army Rangers, that make high altitude jumps which they call it "HALO"
Unlike the civilian skydiver who jumps for fun plus ends the day by
partying, drinking beer, and swapping jump stories, the military
freefall jumper uses the equipment simply as a means to "achieve the
objective," extraction and mission de-briefing. The military jumper
typically carry lots of equipment (150 lbs).
Hollywood occasionally shows HALO missions in the movies such as "Navy
SEALS" as "Rambo raids" [but then Rambo doesn't need to carry O2 or
carry tons of equipment, he can get by with just a 24-foot unmodified
round and defeat an entire division with just a bayonet.]
