Actually, I think that it will have some action between the two squads. Next chapter will be a battle in the bridge conjuction. Next will be taking out the turrets. There may be another chapter too, but other than that, the reinforcements will come in the chapter after that. Things might slow down a bit before they head back out to take the Western Security CP. Some will stay put, while some take the Eastern CP.
Btw,
spoiler:The Trandoshan squad is called Jupiter Squad.
The spoiler wasn't really nessesary, lol. I'll make a profile for them once they are introduced.
