Doucette,
You can find out some basic information about our unit
here. As the 15th has a policy against recruiting members from within their ranks, I do not wish to actively violate that policy. Having spoken to Col Penny about the situation, I will paraphrase what both parties deemed appropriate.
If you are interested in an Army-based light infantry experience with a small amount of supporting assets, the 506th will meet those interests.
If you are interested in large-scale USMC-based combined operations, the 15th is the place for you to be.
