I suggest making it possible to fix certain consumables to certain keybord keys. In this way I could choose to alwyas to have smoke on T, hydro acoustic on Y etc. This works fine in other games (with tanks and planes). I find it quit confusing that the different cosumables is not always on the same buttons and have often - in the heat of the battle - activated the wrong consumable, because the key was now associated with a different consumable than in the previous game.
Keep up the good work
