...how was the cargo destroyed? It has protect-ship and beam-protect-ship on it, and one of your objectives is "Recover NTF Cargo", so you shouldn't have been shooting at it. I have added the if-destroyed-do-not-arrive, but once they've arrived they announce they're going after the cargo, which ought to stop a player shooting at the cargo units.
Briefing Icon: Whoops. Fixing that now.
I can't make a decent-looking background to save my life, unfortunately. If somebody else wants to add one, they're welcome to do so.
I thought of that. I also disregarded it, because the Alexus makes no attempt to run. It's never even in motion, and most people rate getting it to stop shooting at them higher then disabling it if it's not moving. You would have to kill all 4 AAAf beams at minimum, anyways, to make a disabling run on the Alexus in relative safety. The current setup is also the order your wingmen will attack the subsystems and the order in which you're given the directives.
The Echelon's arrival conditions are "And: Is Disabled Delay (NTC Alexus), Is Disarmed Delay (NTC Alexus), Is Destroyed Delay (Pisces)" Why it would jump in when the Alexus has working weapons is, quite frankly, beyond me.
The cargo is intentional. Since the Alexus is not carrying anything, and the Echelon isn't carrying anything, the Echelon's cargo remains nothing. Just for the sake of completeness, though, I've since changed the Echelon's cargo to "Boarding Party".
The Eryines are standard, but they shouldn't pose a serious threat to the Echelon. One wing is after you, the other is after the Echelon but has a low target priority, and if you and your wingmen get close to them they ought to come after you instead. They also aren't as scary as they look: both wings are armed with only Harpoon#weak/Hornet#weak missiles, and one of them has only Prom-Rs for primary weapons. The other has UD-8 Kaysers, though.
Still, I've dropped them both to two waves, along with Pisces wing, the Myrmidons at the beginning of the mission.
I'll take a look at that messages thing...whoops. Added a ten-second delay to the conditions for the Echelon's arrival.
Also, since this is supposed to be an SOC squadron, I upped the AI class of your wingmen from Captain to Colonel.
Altered mission now available.
