Edit - Original method has been patched. Less cost for red talon soldiers, but will have to recruit 4 now.
It's 3250 prestige points for each red talon soldier you recruit to your community in the regular game. I'm averaging about 500 PP per solo game of Daybreak I play and I'm sure you'd get even more with randoms / friends.
You can recruit 4 Red Talon in one community, but for me the tracker stopped at 50 percent so I had to do another playthrough. Guess what tho fam, you can select the same two Red Talon contractors from the start of the next play through and it'll count towards the next community. That brings the total to only
3250 x 2 = 6500 prestige points for the achievement. If you're experiencing the same issue or just want to do it faster than grinding all the points I'd recommend this method.
If your community is maxed out like mine by the time you recruit RT contractors, exile the characters that
-always are crying
-morale is at negative 7 for no reason because "they don't want to talk about it
-are easily frustrated and makes others irritable for no god d*** reason
-Stank breath (no really, it's halitosis)
... or just exile everyone!
Recruit Two Red Talon contractors to your community. Finish the game and select the same two red talon contractors for the next playthrough. Cheevo pops at start of the next playthrough.
