I want the enemies to move around and not just stand in the same place every time.

The enemy we face today will not stand against you.

No enemies stood against the friends for this first scrambling rush.

The enemy stood for different things and must be defeated.

"Because some of his most dangerous enemies were standing in the crowd today!"

At Post 62, despite tank and artillery fire, the enemy stood firm.

I don't think the enemy can stand the strain much longer, either.

As old allies gather for one last battle, even older enemies stand against them.

It's a little unrealistic, but cover still works even when enemies are standing above or behind you.

The two enemies stood glaring at one another for a long silent moment.
