Yes, but the standard bearer can be anywhere in the front rank.

No.

Yes. There is nothing in the rules that excludes these units from getting unit standards.

Yes. There is nothing in the Rulebook that excludes this.

No. A unit may only have a single unit standard bearer. The only time a unit may have 2 standards in it is if one of them is the unit standard, and the other is the battle standard.

No.

If the standard is in the front rank of a unit and all of the regular troopers in the front rank of a unit die in hand-to-hand combat, then the standard bearer is killed.

If the front rank consists of 1 hero, 1 champion, 1 unit standard bearer, and 1 regular trooper and the unit suffers 2 wounds to rank and file troopers, the standard is lost (even though the champion and hero survived).

Standards are captured if:

• The standard bearer is killed and the enemy wins the combat.

• The unit breaks in hand-to-hand combat and flees and the enemy pursues.

Standards may be recaptured if:

• The unit that captured the standard breaks and flees from combat.

• A recaptured standard does not get to be used by the unit that lost it.

Standards are lost if:

• The standard bearer is killed but the enemy doesn't win the combat.

• The unit breaks and flees but the enemy doesn't pursue.

The unit must be broken in hand-to-hand before the standards are captured or lost. Other effects that cause units to flee do not cause this loss of unit standards.

No.

The musician allows a unit to reform if it makes a Leadership roll. The unit can then face any direction with any rank formation. Units reforming with a musician may not shoot.

Only if that unit was fleeing.

Units with or without a musician may change formation by one rank at the cost of half their movement, by two ranks for all their movement. Units changing formation in this way may fire missile weapons, though they are penalized for shooting and moving.
