No. I clearly remember seeing that in the end credits, when I first watched Rambo 3 on TV, in the late 90s. Rambo 3 was a great movie and I liked it more than the first one, because I was a kid back then.

I remember it clearly because that was the first movie I saw exploding arrows. I don’t know if the explosive arrows were made famous in Rambo 3 or in Predator. In any case I watched quite a few reruns of Rambo 3 on TV, and they clearly had that dedicated to mujahideen fighters message in the end credits.

My apologies! Thank you for pointing this out.
