Steam Points can be used during the Movement phase to move the Tank or during the Shooting phase to fire the Tank's gun (or guns!). All unused SP are lost at the end of the turn in which they are generated, so use them all if you can!
Each action has a cost in Steam Points, as shown on the chart below:
| Action | SP |
|---|---|
| Move forward (up to 3") | 1 |
| Move backward (up to 2") | 1 |
| Pivot on the spot (up to 90°) | 1 |
| Grinding (once per turn) | 1 |
| Fire hull weapon (once per turn) | 2 |
| Fire turret weapon (once per turn) | 1 |
