Universal Soldier Sequels

I remember watching the movie Universal Soldier, and Universal Soldier, the return. I'm pretty sure I saw a few other movies which were some type of seqels but am unable to find the names to them. Can anyone help me with the names of them. Thank you

What sequels to what movies?

The sequel to Universal Soldier and Universal Soldier The Return. I could of sworn there were a few movies other than just those two. Thanks for replying, I appreciate it.
