Alright, here you go.
In case you want to know the loadout it's all Apollos for Alpha, all Hercs for Beta. Weapons are Avenger - Avenger Interceptor - Phoenix V for alpha(with Fury - D-missile for me) and Avenger(4 bank) - Prometheus(2 bank) Interceptor - D-missile for beta.
At the start of the mission press F3 and add all hostile fighter wings to one of the F keys, I did it with F8. Then order everyone to just engage enemy and run in there and draw some fire.
It's fine if you don't kill that many fighters, just go in there and draw fire away from your hercs so they can do some damage. After the fighters are dead if even 2 friendly fighters survive they should be able to clean up, especially beta with D missiles. As soon as you hear the lockon warning press "target my most recent attacker" and drop your current target, friendlies can clean it up, just focus on drawing fire and solid defence. If you added all wings to one F key you'll have way better situational awareness.
Aries will always die to sentry guns on insane thanks to the AI firing at full fire rate on insane so ignore it. Go after the other transport going for the node but watch out for its avenger turrets. Just use your D-missiles here, if all your friendlies die before cleaning up save at least 1 D-missile, you should be able to clean up in time.
ETS settings are 0 guns, double shields, normal engines. Use "transfer energy shield - > laser"(you'll have to rebind it, the default binding is on scroll lock) to pump shields into guns. This is more efficient since shield recharge grants more energy per second and transfers are 100% efficient.
