The following makes as much sense:
- An enemy soldier can be either firing or reloading. If he is firing there is no need for me to fire. If he is reloading, again, there's no need for me to fire
- An enemy soldier can only fire at me if he is firing. Since he's firing there's no need for me to fire.
- An enemy soldier fires at me and then stops to reload, since he is not firing at me there is no need for me to fire.
Not applicable to our dojo as we request that everyone check their guns at the door.
