Simultaneous movement

I like the idea of simultaneous movement, but am unsure how to inform the player what has happened as if everything happens at once the player cannot see everything.

Ways of informing players include:

Kills/Losses statistics (as a report)

Showing enemy moves since the last turn as arrows from their previous position (as a layer than can be turned on and off)

Showing enemy attacks since the last turn as arrows (as a layer than can be turned on and off)
