Second mission is very hard, I heard some rumors that devs will reduce difficulty tomorrow. You have to escort some ships on new planet and there is too much mantis coming. Two guys in squad - 9 mantis, 3 guys in squad - 11 mantis. And they all shoot escorted ship, which is unnatural, even if we shoot them, they still target ship we want to protect. Also they have stun and very powerful blasters. We can aid big ship with repair fields, shields or repair target but no chance.
