During the time when I was collecting Hasbro's G.I. Joes, I also found series' that was very similar like them in 1/18 scale and truth is I like them EVEN BETTER and really I still do to this day simply because IMO they have some features that Joes lacked throughout much of the RAH era. They have detachable rubber knives and stuff like that + some awesome cryptic features as well. Many collectors think that these are knockoffs and/or bootlegs but I beg the differ, sure, they didn't have the fancy artwork and bios nor a cartoon & comics like the Joes did but the characters, I found them to be really fun. I sometimes call these guys REMCO Joes. These guys consist of multiple series' and the figures were repackaged and re-branded with Commando Force, Desert Patrol, American Defense, The Ninja Strike Force, and most importantly the US Forces: Defenders of Peace! The years these great series's were in production & and in the action figure isles was 1986 - 1992. My Grandma got Me all of these guys mostly from K-Mart. I believe they were mostly sold there and mostly considered to be an exclusive to that department store.
OK, here they are. Please note like a lot of My collections, they are not complete and are worn by Me playing hard with them back in the day (I crossed them over with My Joes as extra cool characters when I was a kid), not taking care of them and due to age. This is not My entire collection of these guys, I have some others that I misplaced which if I come across them in the future I will be sure to update this section! I also may have placed the wrong weapons with the wrong characters but these are indeed the same weapons that was included with them however. Otherwise these guys are in OK shape! Here they are with My brief commentary!
US Forces: Defenders of Peace, S.I.T. (Strategic Intelligence Team, and Villains!
Protector: This guy has always been a favorite. He is kinda basic but very heroic looking at the same time.
Airman John: He is really cool, a combo of an air-force pilot, a tanker and a spaceman!
