The first time they used the UH-60 in an airborne assault into contested territory (Grenada) they lost three aircraft at one LZ. The 280 has demonstrated that it meets all of the Army's agility goals while being twice as fast and twice the range of existing assault helicopter. With its characteristics the V-280 can pick and choose where to insert the troops while the shorter range 60 and Defiant will most likely have to pick the first (and most likely) one they get to.
