Multiple enemies fire - rotation/movement

Hello!

I am helping one of my students create a game like the old school Ikari warriors. We are making good progress but I am stuck on the logic needed to have multiple bad guys fire their bullets toward the player.

Let me set up a more detailed example and then I will ask a few questions

Okay so Badguy1 badguy2 and badguy3 are on the stage. They each decide to fire. Using duplicate movie clip a bullet is created. We need to start that bullet at the current position of whoever fired it and then move it toward the player. I know how to do one badguy firing but I don’t know how to pass this info to multiple bullets.

How do I pass this information to each bullet?
From reading posts it seems attach movie clip is preferred over duplicate movie clip. . what is the reason?

I appreciate any help you all can provide. I did read through several posts but I did not see any that addressed multiple badguys on the stage firing. If I missed something feel free to point me in the right direction.

THANK YOU!
