You can see it in action in the recording of the recent dev stream: https://www.twitch.tv/videos/167547770 It's called Ambusher Jump Jets, and what they do is give you a strong push up and forward. Looks like about ~40m jump forward overall, but it seems you can jump more upwards, if you need to. The forward jump is pretty fast, and comparable to Icarus speed. However, actually scaling objects with it is likely to be more than tricky. You don't actually get any aerial control, it's basically a super jump. Activation immediately burns all energy, and then there's ~7-12 second cooldown (numbers are rough estimates, and will change with upgrades). They also intend to make an interaction with max rank of Aerial Combatant, that getting one kill will instantly regenerate all energy for the Ambusher Jets. Overall, it's indented for experienced Light Assault players, and will be more expensive to upgrade, sort of like Adrenaline Shield for heavies. Personal take: I'm excited that we're still getting attention from the devs, even though lately LA has been in the best state since launch. I'm not sure if Ambusher Jets will actually be viable. I do like the fine motor control provided by Skirmisher Jets. That said, I always wanted to like Icarus for their high speed, but lack of horizontal movement just killed it for me. Ambusher Jets solve that problem nicely, so it's pretty great for escaping, or just jumping in with shotgun blazing. Lack of horizontal speed has always been the issue with shotgun and SMG loadouts.
