I had an incident this morning with another Mobius commander in a "security operation" (PP version of a CZ) in Hudson space. I sided with the opposition since I'm an ALD supporter. A commander in a 'conda started attacking me in my FAS.
Being in the home system of a security operation, I can understand that the commander wasn't looking too closely for other commanders on his sensor.
While being fired upon, I targeted him so that I could send a direct chat message while boosting away.
I quickly typed in "Mobius".
1-2 seconds later he stopped firing at me and apologized for not realizing that I was a commander and not an NPC.
My shields were gone and I took a bit of hull damage,
but due to some quick communication, we were able to put a stop to what could have been a very bad situation.
If you are being attacked by another player, send him a quick
DIRECT chat message. A 'local' message could be easily missed due to all of the NPC chatter in a combat style zone.
