From what we could see of the trailer, that seems to be how the jet packs (and come to think of it the SRV boost) work.
Hmmm, I do wonder how long the jetpacks can fly for? - or if they are simply going to be 'jolly jumpers' with brief moments of flight before recharging on the ground is required. I'd love to see a wheeled troop carrier similar in design to the M577 Armored Personnel Carrier from Aliens. https://alienanthology.fandom.com/wiki/M577_Armored_Personnel_Carrier
Although a hover style troop carrier might be easier and more practical (in terms of flexibility on rough terrain).
I believe there needs to be a means to move larger numbers of land forces rapidly over potentialy extended distances, whether that be via wheels or via hover.
