Birth control via surgery..

ELP • 23 year old animal lover.
Okay so this may be a dumb question and general knowledge but I'm curious. 
If someone has a hysterectomy or a vasectomy is either reservable? Or are they both permanent?
I am asking because I do not want kids. I am 20 and my husband is almost 19. He's is the marines and plans to retire from it so well be moving around a lot and I will be on my own a lot. Also he doesn't want kids either. We're both yo young and do not want to even think about kids until we're 100% financially stable. But the thing is I do not want them at all... 
I was wondering the requirements for either of the surgerys. What one is cheapest or easiest/quickest. If you have any idea. 
No I am not forcing my husband into this. It's just a general question. Lol.
