Will the officer uniform not give friendly fire penalty for damaging friendly structures made by players in your regiment? Can builders use it to clear out bunker pieces and blueprints?
No. Friendly fire is tricky. We'd love to allow anyone to dismantle any structure (that would make building a lot more fun and sandboxy), but the unfortunate reality is that we always have to account for griefing edge cases.
For example, all it takes is for 1 player in the future to build a huge bunker base, have the front line reach it, and then destroy it on their own during a critical battle. That's unlikely to happen but as we often see certain players will try their best to test the limits of what can be done so we have to constantly think of all the possibilities and be careful.
Having said that, we'd like to hear about the specific scenarios and pain points to help guide future development of builder features.
