I saw a movie in the 90's that was about some incarcerated teens (I believe) that was let out to go to a country where they were to rescue someone or some people. it was not the movie that was called the band of the hand. the one part that I remember the most is that one of the guys (a black guy) had a bag with a snake put over his head and ended up biting the snakes head off. it was a B movie for sure, but it has stuck in my memory. if I need to post this somewhere else please let me know. Thanks

Soldier Boyz (1995) ?

Here's the full film. A scene like you described plays out around 39 minutes in.

^ And you know it’s a badass movie because they replaced the ‘S’ with a ‘Z’!

OP - You forgot the best part. "What's for dessert, mother fucker?!"

you will never know how long I have been looking for this movie. you defiantly figured this one out. Thanks
