Feats are restricted to certain classes, and may only be used with the DM's permission.
Feats marked with (CA) are taken as an option for your 2nd level Combat Ability feature (you take it at 2nd level). Taking one of them removes your 4th level Ability Score Increase feature (you do not gain it when you reach 4th level).
Note that magic does not exist in the setting of Girl's Frontline. As such, assume that magic related feats are disallowed, such as Magic Initiate or Mage Slayer.
T-doll
Disobedience. You lose the Laws of Robotics feature and add +1 to either Intelligence, Wisdom or Charisma.
Close Quarters Fighting. Being within 5 ft. of a hostile creature doesn't impose disadvantage on your ranged attack rolls. You gain +2 AC against attacks made by creatures within 10 ft. of you. You gain proficiency in Athletics. If you already have proficiency in Athletics, your proficiency bonus for Athletics is doubled.
Overwatch. As an action, you may go into overwatch. Until you move or take another action or bonus action, you gain +5 to your passive perception. You may also use your reaction to make attack actions as if it were your turn, or use your Combat Ability that takes an action to use. As a part of this reaction, you may also activate your Combat Ability that does not require an action or bonus action to use.

Horn of Mars. (CA) Until the end of your current turn, for each other allied Rifle T-doll within 30 ft. of you, you may add up to two points to your attack rolls when determining whether you score a critical hit (i.e. if you have one allied Rifle T-doll within 30 ft. of you and roll a 19 on an attack roll, you may add 1 to it to make it count as a 20, and thus a critical hit.)
Passive: Each time you make an attack roll, choose two T-dolls within 30 ft. of you. They may add 1 to their attack rolls when determining whether they score a critical hit. You may not use this on the same T-doll more than 3 times at once. (If two or more characters have this ability, they may apply it to a single T-doll up to 3 times each.)

This effect lasts until the beginning of your next turn.
Submachine Gun
Etching Overload. (CA) When you activate this feature, your AC improves by 1 and you subtract 1 from all damage rolls. At the start of each of your subsequent turns, add a further +1 to your AC and a further -1 from all damage rolls, up to a total of 5 times. While this ability is active, you may use it again to reset your AC and damage modifier, and then subtract 1 from your AC and add +1 to your damage rolls.
