A nice addition to the game's equipment list would probably be a small medikit, which does not need to be manufactured but can be bought. And 2 of these small ones should be in your starting equipment of your first skyranger.
This can be very interesting for early missions, because you probably want to allocate your manufacturing to more interesting stuff first, like laser weapons. Or worse, you start a mission, but don't have a medikit produced yet.
Because it can be very frustrating in your first mission seeing one of your best units bleed to death from a fatal wound and nothing you can do to save him. (One of the early lessons in game development is: the first experience in the game should never be frustrating)
The kit itself takes only 1 inventoryslot (instead of 2), but has less charges of healing,stimulant,pain killers. I was thinking 3, 4 or 5 charges.
