Combat 6 is the 13th of the 24 Puzzles in Subterfuge.
Take control of Feld.
Very similar to the last puzzle, but with a twist. What you need to know here is that two subs that cross paths while travelling between the same two outposts will engage in combat.
Understanding when to engage in sub to sub combat and when to avoid it entirely is an important skill.

Move at least 9 drillers from Garfield to Vaccarino and then send all of the subs at that outpost to attack Feld.
