The most worthless Duty Officer power in it's current state. A additional level one Security Escort is worthless to my VA 1 (Level 51) Tactical character.
Here are the differences by quality.
White: 20% chance: Beam down a additional level 1 Security Escort I crew
Green: 20% chance: Beam down a additional level 2 Security Escort II crew
Blue: 20% chance: Beam down a additional level 3 Security Escort III crew
Purple: Beam down an additional level 4 Security Escort III Crew
The Purple version is supposed to be 100% to summon a Security Escort based off the tooltip, but currently it does nothing.
This sounds like a bug. I'll look into it. It should be beaming them down at your level.
Edit: Fix is now in the pipeline.
Last night on KA Ground, I got a guy who was security team I and didn't seem to have a weapon, he then beamed back out after doing the idle animation for about 10 seconds. The other guys who beamed in with him stayed and helped in the fight.
I just figured he beamed in without a weapon and then he thought: "Hmmm, lot's of Borg, I have no weapon, 'Hey Captain, I'll be riiiiiggght back...' "
Just thought I'd let you know, don't know if it was a bug or not.
