Might be too late for a reply...
What does "speed" mean on your list? Is that the time between shots? The time it takes for a character to be out of cover before firing? Something affecting initiative? It doesn't seem to be rate of fire, since you listed that separately.
I'm mostly asking because I saw the Assault Rifle listed as "Medium speed" despite having a full automatic mode, compared to a "High speed" pistol.
Also, what's the practical difference between "semi" and "burst" fire?
Is there a practical difference to the "special" mode or is it the same as "single shot" for heavy weaponry?
