when a squad is delayed to attack someone, does the player being attacked get an alert on their radar that they are being attacked before the squad has even left its origin? If the person does an "incoming attacks" scan on his own colony, will it include that delayed squad in its report?

Nope, it is invisible. It is as if the attack is being sent the tick it returns to the normal ETA.


For example:

If you put a 1 tick delay on a 3 ETA attack, the squad will show up at the beginning of the next tick when it returns to normal ETA.

Nope
