The following information was provided by Ivan Feliciano.
The 1/61st Inf Reg (Roadrunners) was part of the 5th Infantry Division (Mech) during the '80's. It was in 1989 that It was merged into the 6th Inf. I believe 5/6th to be exact. We were deployed to Panama just before the change in May of '89. I was with D Co 1-61st during that time.
