Low Altitude Drop At the start of your Movement phase, you can declare that a unit from this Formation will enact a low altitude drop. If it does so it must take a difficult terrain test each time it moves over terrain that is more than 3" tall during this phase, and cannot Jink until your next Movement phase. However, until the end of the phase, units that disembark from models making a low altitude drop using the Grav Chute Insertion special rule do not scatter.
