you can go to the visibility option on the top left corner and disable squads so you dont see them and cant select them.
Well that is a solution, yes, but it is still 2 actions for 1 move! hehe
Here is a common scenario...
less than a minute left until the tick ends... you refresh your client and realize that the enemy has built a new op and has launched their army to it, you want to nuke it, so you find the closest nuke and it happens to have squads on it, you go to visibility options, uncheck the allied squads box, select the nuke, select target, launch nuke and get a message saying "your action was not performed because a tick has passed!!"
Seconds become very valuable in situations like this...
And reminds me of a suggestion I have about visibility options, which I will post in the proper section.
