A rank 3+ Ultramarine initiates the defensive stance Considered Defense from the First Founding book. This allows the brother, as a free action, to change the benefit between +4 armor points from cover, move agility bonus in meters as a free action, and gain an additional reaction.
The question -
If it is this Ultramarine's turn, and because it is a free action to change between the benefits, may the brother who is within say 2 meters of an enemy...
1. change the benefit, as a free action, from "additional reaction" to "move agility bonus in meters as a free action"
2. move his agility bonus in meters as a free action to move into close combat with the enemy
3. as a free action yell "SUFFER NOT THE XENO TO LIVE!"
4. perform swift attack as a full action
5. change the benefit, as a free action, from "move agility bonus in meters as a free action" to "additional reaction" (to be better prepared for attacks back)
these 5 steps in one turn?
The Battle Brother is simply walking to the target, shouting, attacking, and preparing for attacks back. I see no issue with it in the rules and it does not seem to take up alot of time, possibly 5 seconds.
