What ever happened to Combat Support Companies?

[santini88]

This may not be the correct forum for this question, but I guess its a good starting point considering the wealth of knowledge available here

I left the infantry in 1977, I was a member of the 1/15th Inf Combat Support Company. Composed of 4.2 Inch Mortars, Redeye Air Defense, Scouts, and Ground Surveillance Radar.
That being said...I visited The 1/15th's web site and noticed the battalion had been reorganized with no CSC. Can anyone tell be when this happened?

Thank you
