Super pogo stick.

Your soldiers carry pogo sticks on their backs. The unobtainium springs capture the energy of their descent, and when they are in a hurry give it right back; when they hit the ground they decelerate over a split second then bounce right back up nearly as high as they were. For long drops you need an exosuit on because it is still a lot of work for the quads.

The super pogo will be good for other things too. Of course you can move quickly on it although the exosuit itself is about as good; mostly this is useful if your exosuit is damaged or you don't have it, but you have the pogo. A changed setting will keep the spring coiled and after jumping down the soldier can stay on ground level; the pogo will gradually uncoil the spring if desired to (more dangerously) stay coiled until deployed. A soldier can gradually coil the spring by making a lot of little jumps and storing the energy. That can be used for an ascent, or punching open doors.
