How about a standalone 40mm grenade launcher with HE, buckshot & flash? It can be attached to railgun & rifle for quick use without switching weapons but slightly slows down overall aiming. As a trade-off, addition of this grenade launcher to loadout can reduce hop distance due to extra weight while its ammo is already limited.

Give the commando a medkit with limited capacity and upgradable effectiveness. Might as well deploy expensive jump jet medics. Add a nice sword if you want more fantasy.

Imagine a squad of these heros on the battlefield. Legendary. Halo-ish if you ask me.

A Tiberium Wars mod that features Tiberian Sun including Firestorm? Yeahhh! I've been thinking of this for CoH2 though, gotta love its cover system favouring infantry. But this exists, and it will impress. Cheers!

Havoc suit in Sentry form? Meh. While without pilot, it should enjoy full mobility including walking and hopping. (perhaps even longer hops for not carrying pilot) Jump jets can be noisy, right? Not exactly handy for stealth while it makes a juicy target for enemy SAMs. Force commanders to use it wisely. Let the commando engage the jump jets on low output to boost running speed. Maybe make a navy/marine variant that is amphibious, can cruise at surface, dive & walk underwater for limited period of time with upgradable oxygen supply, and has powerful propellers without cooldown limitations instead of jump jets. If you like it, even the jump jets and propellers can be upgraded. I like the idea that the suit aims the railgun slower without pilot's own strength.

No optics for the railgun? Make the railgun capable of shooting at air targets. Also make the weapons customisable. Options can include replacing the missile pods (tiny homing missiles inspired by Ironman?) with launchers loaded with bigger but less missiles. Difference would be anti infantry or anti vehicle. Maybe add smoke grenade launchers and flares?
