Columbia 1950's Army ranks

This is taken from a booklet sent to me by Sarge Booker.
It’s a typical booklet of the period, not great on detail but serves it’s purpose, in all a nice little booklet for giving the general idea of the ranks.
I’ve guessed that the General’s stars have the Columbian arm on, also the shoulder buttons.
