The Tenth mission in the Earth Alliance '71' path and a fairly manageable one in spite of the various powerful enemy ace units.
Start by building what meter you can while avoiding taking damage until the Buster spawns in then go over to it and take it out using your built up meter, it should go down quickly making the Justice show up, the Justice can take a beating and you will want to use Hyper mode if using pilot SP as the SEED mode activation makes him immune to slow down.
When engaging the Freedom try to work with your allies as he is rather durable and can just decide to obliterate you with his beam special so try and keep meter for Hyper mode in case you need a panic out option, afterwards you can move forward with your allies making sure to clean up any enemies on the way before taking out the HQ.
For the Second part you just need to take out the Archangel as it flees, as long as your suit isn't too slow and has good damage options it should be pretty easy as the Astray's can provide meter for you if you need it, if you are having trouble with this bit the Assault skill increases damage against ships though i chose not to use it in favour of Rookie to keep raising my stats.
