Thanks for your replies Daddog and Drano!
Specifically applied to last FSO, my squad of 15 was assigned to defend a target that was eventually attacked by exactly 2 110's at nearly T+60. The 110's achieved surprise by finally arriving under-dar and had an initial success on their attack before we arrived to kill them. This is a good example of how there are still enough variables left in FSO to keep everyone guessing.
EDITED: text removed
There were four targets to attack, and four targets to defend? That doesn't seem like too many to me, but I didn't have to write the orders.
