Thanks for the explanation. To repeat (and also see Mahtamori's post) - as with other situations where multiple Troopers are activated at once, if any of them can declare the Skill you declare it with all of them, and the ones that couldn't declare the Skill Idle instead.
Antipode A can declare Close combat attack, but can’t declare Move. Antipode B can declare Move, but can’t declare Close combat attack. Can the pack still declare move+close combat attack?
Yes. If any of them can declare Move, you can declare Move with everyone, and the ones who can't Move will Idle instead of moving. If any of them can declare CC Attack, you can declare CC Attack with everyone, and the ones who can't CC Attack will Idle instead of attacking. So A will Idle-CC Attack, and B will Move-Idle.
