Summary (a quick, 2-3 sentence summary): I suggest changing this to special 40mm grenades in the M203 style; each a self-contained round of ammunition which cannot be hand-thrown.
Benefits (How this will benefit the server and game as a whole): M92 gunners would have their own pool of ammo to draw from, and as such, that ammo could be made much more available and convenient. It would also allow the grenades to detonate on contact instead of as time delayed hand grenades, eliminating alien meta-dodging. Furthermore it would bring the M92 up to par with the SADAR as an explosive weapon, as it carries plenty of ammo compared to the SADAR's scant loadout.
Details (Description of how you think this would work, the benefits, etc): The specialist box would have several cardboard boxes of grenades inside to put in their backpack, with the grenade bandoleer as a ready rack of grenades. They could also receive some new ammunition types like buckshot, flare, or HEAT (armor-piercing type) that would not make sense as conventional hand grenades. Science could still make more sophisticated grenades by combining a shotgun shell with a grenade casing for things like polytrinic acid foam and space lube grenades. What joy. As a bonus, move the grenade bandoleer from being a belt to being webbing, so a grenadier can also carry magazines for a rifle.
Implementation (Optional, if you have an idea how to implement it): Here's some sprite inspiration. Simple stuff. Note the copper-capped shells are HE / HEAT, the middle ones are smoke markers and flares, and the M592 is the shape of a buckshot round. Colored bands help with identifying one round from the next.
