Referring to A20.52
A20.52 GUARD FP: A Guard whose US# is < the total US# of its prisoners may not attack any unit other than its prisoners except in CC and may not use a SW, Interdict, or Kindle. A Guard’s FP is halved for attack (but not defense) purposes when attacking non-prisoners in CC.
Q. Imagine 4-6-7 Guard with a full squad prisoner and an enemy 4-4-7 in melee. Can the 4-6-7 attack them both or is it limited to only attacking the prisoner? If it can attack both, does it attack 2:5 (half FP) or at 4:5?
It is not clear to me if including the prisoner is enough to attack against everyone at full or if including the 4-4-7 is enough to make everything half firepower. I looked for existing Q&A but couldn't find any.
