When your detachment has one or more Blast markers on it, you must pass a Leadership test before you can move it under orders in any phase or set Overwatch orders.
[TODO: What happens if you try to set Overwatch orders and fail? Default to Advance orders I presume, and lose the chance to use any other orders? If you pass the test to set Overwatch orders, do you get to move up to 5 cm under those orders without a further test?]
|A detachment that is subject to the Broken condition is not under orders — so, a Retreat move does not trigger a Leadership test.|
Roll a D6: If you score higher than the number of Blast markers that are on the detachment then you succeed — you may make whatever moves the orders permit; otherwise you fail — you may not make any moves with the detachment during this phase.
If your detachment currently has 15 or more units in it, add +1 to the score.
A roll of a natural 6 is always a success, no matter how many Blast markers are on the detachment.
