Well, what do we have here? A new vehicle!

Now, I will say, it does look much like a hollowed out Brute Prowler.
The inner workings of the gear mechanism look cool.

This set gives us a Spartan, 2 Brute Warriors and a Grunt Conscript.

As with the other sets from the Summer 2020 lineup, this has an alternate build as well!
When O first saw the ALT build, I thought it looked much like the skitterer from Halo Wars 2. Perhaps that was the intention? Also, you can build a Banished barrier.
Those both definitely fit within the Banished aesthetic.

Here is the official text blurb from Mega about this set:
