IIRC (which I do:rofl, both Brilliant Lances and Battle Rider were TNE official space combat wargames.
Thank you. I actually own those games (never played either--hated TNE--I think Battle Rider is in brand new condition with none of the counters punched), and I forgot the edition. You are correct, of course.
And even though Power Projection is designed by the people at BITS (who usually published T4 supplements), the rules are valid mainly for CT and T20 (and maybe MT?).
I haven't read it, but PP is a Traveller adaptation of Full Thurst.
