Is your AR-15 modded?

yes, mod 3 with both skills trained to level 10 and equipped with her special ammo from the night battles that gives her a massive damage boost compared to hv ammo. shes in the team because shes overwhelmingly powerful and a more consistent rate of fire.

the main thing about fighting Judge is having 2 shotguns in the front row at the top and bottom. its because Judge has like a split shot that aims from the outside first and closes into the middle, but its weak so it cant get through armor units fast. so with your two shotties on the frontline you can move an MG up to the frontline in between them and its basically the safest place for her. so count on that one MG to survive the longest and put out the most damage on Judge.

if the other 2 girls you have are MGs they will probably be at the back anyway, but if they arent then move them to the back corners. because Judge jumps in and leaves that area of effect on the back row girls. so if they are in the second column bunched up with your 3 frontliners then the frontline is going to get a lot of burn damage. its kind of a sacrifice play to let the 2 girls in the back corner burn to save the health of the frontliners. its all about the 2 shotties and the 1 MG that will be there the whole time.
