Most squad-based tactical games in the vein of x-com allow the player to rename their soldiers.
90% of the time, players use this feature to make notes about their soldier's capabilities or role in the squad, leading to teams with stupid names like "Bob Machinegunner" or "Bill Sniper" or "James Medic." Or even worse, "Shotgun 2."
I've always hated this. Could we just have a separate field, which is displayed with the name (like their rank), which allows us to enter a comment without renaming the soldier? Or even just provide a dropdown of preset roles we could assign our soldiers? This could also be used to allow us to sort our soldiers when equipping them, allowing for easier management of soldiers within standardized roles. Even better, it could allow us to define default loadouts to soldier roles in order to reduce some of the micromanagement required when equipping squads before a mission.
