First, let's pretend all the existing infantry are now inaccessible, and then need to be built back up from scratch (rather than tweaking each one, removing certain ones, etc). Of course, I'll refer to stock Renegade's infantry, but again, as a reference. I'm sure you're already taking this approach, but still.

-The basic class, the minigunner, should have a pretty basic rifle that can do roughly the damage the current laser rifle can do vs infantry, minus the fairly heavy anti-vehicle capability. This means they're consistently useful, but due to their health, aren't going to be a huge threat.

-The second class, rocket soldiers, should be basic (free) infantry. Their movement speed should be slower than minigunners, but they should still have access to homing rockets to deal with vehicle and aircraft threats. They wouldn't be able to huge amounts of damage (unless in groups), but would act as a sort of "go to" free counter to vehicles and aircraft.

Due to their slowness and lack of armor (more than minigunners but still not much), they'd not be a "hurrr everyone get this!1" unit. Just use the shotgunner model (thus replacing them).

-Engineers should remain basically as they are (unless you can find a way to have a weapon that does extra damage to MCT's without modifying the warhead text). Though, maybe an added bonus of being able to take over neutral structures (if ever put in)? It'd be neat to change up the gameplay.

-Flamethrowers should become a purchase unit, and have a boost. I'm thinking an increase in spread, along with a damage increase. I'm not sure if .mix files can use .w3d replacements, but I remember I once messed around with the flamethrower emitter and made the spread larger (and messed with other settings). It actually looked pretty cool- it also fit a hell of a lot more, because the current little exhaust fume gun looks like crap (which fit considering its shit damage).

Because you're probably going to give infantry infinite ammo, might I suggest removing the flamethrower's need to reload? Then, give it a secondary fire mode that shoots a little ball of fire (that has a slow rate of fire so you'd have to wait to use either firing mode).

Basically, make the flamethrower not suck (I haven't played Fjords so I dunno how you handled this, but I'd imagine you'd have to change it up at least a little if you plan on restructuring infantry).

-Grenadiers could... uh... actually, I dunno, but I'm positive you'd come up with a better solution than me anyway (if you haven't already), so yeah. If I recall, you gave them a "cluster" secondary fire, which is pretty neat. Though, they should also be purchase units, so they can actually be useful.

-Technicians/Hotwire can be the same as they are. Or, you can go the badass route, and make them able to place down those sentry guns that were initially planned for them. Of course, that would probably be a pain to implement, and would require some balancing. But damn, it'd be cool.

Also, you COULD switch the roles of Engineer and Technicians (which makes more sense), but that'd mean you'd have to find a replacement for Hotwire. Which, I dunno if you want to find/make a skin/model replacement just for that, so, not really necessary.

-Stealth Black Hands, I feel, could stay- but be given a different weapon. Maybe just the regular autorifle that minigunners would have? Either way, the idea of infantry combat being actually useful (unlike how it was in C&C95) means the approach to it should be treated differently. Given that, Nod should have expanded abilities in infantry combat... namely, stealth.

-Commandos should be given the regular sniper rifle (because FUCK ramjets), and a single remote C4 (as well as a timed C4). Not enough to take down a building single handedly, but enough to aid a base raid and thus be a threat to buildings (instead of just "hurp durp i snipe u"). GDI's should use Logan's model (because Logan is cooler), and Nod's should use the Black Hand Sniper model.

-Chem Troopers should basically be how they are now, but balanced to be up to par with the new flamethrower infantry. The weapon itself should be a more "concentrated" jet of chemicals, so it functions a bit different than the flamethrower (so, y'know, variation and all that rather than the chem trooper being "hurr same thing but better!"). It shouldn't necessarily be able to do more damage (it should be about the same, maybe a bit more) than the flamethrower, because they have the added bonus of being able to walk through tiberium.
