I think just splitting the two values into two seperate categories would solve the problem nicely.
A 'Normal' (meaning strategic) Speed Value and a Combat speed value. And of course the bonus movement atribute could be applied two speed types differently so you could have things like Combat Drives which generate a less strategic bonus speed but more combat speed.
So a Quantum Combat Drive might only give you 2 bonus moves instead of 3, but you'd get an extra speed point in combat.
