East KY National Guard

Looking at 11b as a whole, undecided between Active or Guard. Thought about going Guard to see if it’s something I could do long term before going active (unless going guard to active is difficult I’m not sure) 28m with a family. I would hate to uproot my entire family for nothing. All I’ve read is the infantry is a young man’s game so I guess it has me hesitant and discouraged, any feedback or advice is welcomed.
