Euhm...well, yes, if the good old "Flying" isn't good enough, you can increase altitude with the setpos command, as so:
unit setpos[(getpos unit select 0), (getpos unit select 1), #]
unit= name of unit
#= height in meters above ground
And as to making other parachute, the "easiest" way would be to create a bunch of empty parachutes, set to "flying", name, and then move in soldiers with the moveInDriver command (s1 moveInDriver parachute1). The other way would be to "misuse" a HALO drop script by making the chute opening height and the starting height the same...eliminates the need for individual parachutes for each and every soldier, at least.
Specify, if this is not what you needed. Otherwise, g'luck! :thumbsup:
Wolfrug out.
