Battles are a mix of turn-based strategy puzzles on a set map with enemies that can move about, random item nodes and heliports/command nodes, from which the player can summon their own echelons, or support echelons, which are echelons that the player's friend sets on their profile to be used by others, and real-time battles with enemy echelons. The player plays as a newly recruited commander of an area who commands the T-Dolls in battle, and organises the echelons as well as the T-Dolls' wellbeing. Girls' Frontline is a moe anthropomorphism game in which the player controls echelons of android characters, known in-game as 'T-Dolls' or 'Tactical Dolls', each of which represents a real-world firearm.
