I was playing around with adding skill points in the "STO Character Builder" and there was a tactic that I'd somehow gotten at RA level that intrigued me, but I can't remember where to spend my points in order to obtan it.
Basically, the tactic was, if your hull gets below 50%, another ship appears and helps you out (similar to the Security Escort ability, but the ship appearing is automatic)
If there's anyone out here who can help me, I'd
really appreciate it!

Thanks so much!

Of course, most of the times the "Help" arrived I was finishing off the enemy target anyway, and during the CE battle it was at the first stage so at least the helping ship didn't run into Large Frags... it did go straight in to 5km and promptly wasted though.
It's a trait you get automagically once you pass RA3. No need to worry about it.
It's a VERY low chance of another ship appearing and helping you out on your current target. Im my case, I was in a escort and getting whomed by having been jumped by 3 ships - when it appeared and helped me finish off the last one. it was labeled as a Ambassador-class, even though it ddn't look anything like a real Ambassador. Wish now I'd thought to get a screenshot - at the time I was "WTF??".
