This actually sounds super rad and kind of conveniently plays into an idea I had for this level of sci-fi technology.
How do you feel about stuff similar to MAX suits from Planet Wars 2, or the power armour from Fallout? I was envisioning something like an exosuit that acts as kind of a platoon heavy weapons platform with different hard point attachments for various weapon configurations and the mechanical nature of the suit lets it carry ample weight, making engineering applications invaluable or breaking through hard cover like concrete. A weapon idea I was toying with is kind of like that rotory twin tubed rocket launcher from Halo, except it goes between a minigun and a scatter gun.
Obviously, like any piece of equipment, it needs to be maintained and fueled up on the regular and it would give off a similar radar or IR signature to a light utility vehicle and while it would ofger a lot of protection against small arms fire, heavy weapons would absolutely be a nightmare for it. Also in case of suit failure or emergency, it can be evacuated relatively quickly and have a carbine kept in an external panel for the driver, as well as have the option to have cargo containers attached to the attachment points so it can carry a lot of a squad's equipment on marches or supplies in general.
One advantage it would have over conventional infantry is that it can be dropped from low altitude without the need for rapel lines so it can be deployed to secure landing zones for the platoon under fire.
Regardless! I am totally going to work on something because it's been a while since I've done am original sci-fi kinda game.
