Out of command

When is a unit said to be out of command for the purpose of a discipline test.

EG. A unit starts in command and proceeds to march move across the table.
At the end of his 1st move he is still in command range.
He therefore starts the 2nd move in command, but ends the move out side of command range.
he must now make a discipline test (for moving 2x). Is he considered?
A. Still in command because he started his move in command?
B. Outside of command because he has finished his move out side of command (when the test is required)?

If the answer is A? Is it then true that if a unit is considered in command when it is 1st activated does it remain so for that activation no matter how far away from the commander it ends up?

I'm sure the answer is in the rules somewhere, I'm just not seeing it

cheers

Convention has always been the test is taken with regard to the end position of the unit after movement.

Not sure if its explicitly stated anywhere but that has been the way its been played since way back.

well the momentum is when you take the test. As the test is taken after the movement, then the situation to be taken in consideration is after the movement.
