If you target a teammate and press spacebar, you shoot them. If you select a drone and right click a teammate, it doesn't shoot them. This put engineers at a bit of a disadvantage in spars.
Bots may or may not have the same issue, I have not tested it.
This also applies to other allied things; drones won't shoot friendly drones, bots, bases, etc.

I have a tag called "pvp side" that I can utilize to make like a, side A vs Side B spar. This bypasses team agro and has it's own rules that makes the two sides automatically agroed to each other without having the hate leave the PvP Side galaxy.
I don't necessarily know if we want to create a way to sick a teamed asset on a team mate outside of an evironment where it's done by design. An equal amount of people may just be annoyed that they are being murdered from a miss-rts input via their allies assets.
I've been waiting to use the tag in a fleshed out game mode.. but I could just make a colo like thing that uses it.. I'd just have to handle like not letting people leave the environment PvP Sided' which I haven't necessarily worked out the kinks for yet
