Disciplinary Action - Trueborn difficulty

See title. I've been stuck on this mission now for multiple attempts. I feel like the game has gotten alot more difficult since the last update. Can't figure out how to beat it. I feel like every engagement the enemies just focus down 1 of my mechs to death so after every wave I'm working with less and less until by the end its me and like 1 other lance mate. Any tips tricks, star composition ideas that have been successful for everyone else.
