Thread of Dread can be beat on mental by rushing with 24-25 kirovs right after the start, luckily the first nuke wave mostly targets psicorps bases, so you have plentiful time to get these kirovs, then rush with them to kill ANY nukes you can, spread them out in groups of 5-6 and attack the 4 nukes all at once, the enemy might be forced to either spread their AA or just target one group of kirovs, this is the way you can kill the nukes, rest of the mission is just defense and slowly pushing your way through.
