Can a National Guard personal have a Military Wedding? And what would be the Dress Uniform?

Yes, look at AR670-1 and wear occasions of retirees, former soldiers and ARNG/USAR. The appropriate uniform would be the ASU worn as dress blue. You may do full size medals or ribbons, pick one. The Groomsmen, if Military, should be in the same uniform.

If the wedding is before 1800, the tie is worn with a four in hand knot and headgear. If after 1800, the bow tie without headgear.

Yes you can. The issue at hand will be the logistics. Even in the Active Component folks avoid doing it due to the headaches, but it can be done with timely and proper coordination.

A couple of guys I served with wore their Class A's when they got married.

I'd hold your horses... you have other things to worry about.

A military wedding is based in tradition and generally includes a chaplain, uniforms and Sabre’s/swords. Contact your unit Chaplain. Good luck.

Absolutely. You would wear your Class A’s in accordance with AR 670-1.

You earned the uniform the same as the rest of us. Class A uniform would the one to wear.

ASU's and worn in accordance with AR670-1 is allowed.
