Metal Soldiers, American G.I.s, Fred Bronner

Hello! Never posted here before. These guys have been sitting on various shelves of mine for years. They were a gift to my Dad in the early 90's, he passed away shortly after and I've had them ever since but never gave them much thought. Suddenly got a little curious about them, their history, rarity or anything really. Not looking to sell them but would like to learn what I could about them. If they are reasonably rare or valuable I want to make sure to stop storing them out in the open and get some protective storage.

I did some googling but couldn't find any other soldier toys or boxes that looked like these. Any insight any of you could provide would be much appreciated!
