The goal of any HALO/HAHO mission is the SAFE delivery of men. To accomplish this you need a reliable, stable, easy to handle predictable parachute. No Tactical Parachute System meets this need better than the UM-1 because no other system uses the Jalbert Parafoil.
The JALBERT PARAFOIL is the most reliable, stable, easy to handle predictable parachute in the World and in that regard it has no equal.
When it comes to something as serious as a HALO/HAHO mission why give the soldier less than the best.
