If you read the card thoroughtly, it doesn't say "open area", which most likely means you can put a monster from your field to the drop zone after attacking with them to call 3 grade 1s during the attack phase for 3 extra attacks. Since this is a counter spell, it can be activated in anytime as long as conditions are met.
