Explain why it's good for the game

The Grenade Satchel and Fix-o-vein are two very under used items. Mainly because they are barley available.

Fix-o-vein only lives in surgical trays, yet is never really used in surgery because all its good for is fixing IB a bit faster. And Shipside doctors dont need to worry that much about fixing IB fast.
But the only surgery that HM can even do is IB, and they need to worry about their speed. Fix-o-vein is infinitly more usefull in the hands of HM then for doctors. Price migth change though.

The Grenade satchel is barley even used. Only Ot and grenade spec even have access to them, wich is kinda silly. They arent a spec spicific item like the rocket bag. Anyone can carry grenades, and there is even a Rifelman version of the grenade launcher.
This should allow people to make more grenade centerd build without having to sacrefise their entire loudout for it. It takes up the backslot, wich is incredibly valubel, so i belive that is fine balance wise. Besides, you can already get grenade satchels from OT or the leftoer one from spec. Its just less annoying to get as normal riflemen. And ComTecs can just chose it as their bag if they want to go wild with C4 or satchel charges. I definitly would want to try.
Btw, did you know you can fit engi kits in the nade satchel?
