In the 60's, in the pre DCI years, a lot of emphasis on the judging sheets was really on performance execution. This was an era before highly creative and elaborate drill designs came into being that accelerated in the DCI years. As such, how one marched and played, really was what got Corps high scores. This was the era of the " Tick System ", where a tenth ( a " tick ") was deducted off the sheets by judges for bad execution by individual marchers in Brass playing, Drums playing, Color Guard Equipment work, and Marching ( called" M & M"... Marching & Maneuvering ).
The reason I mention this on this thread re. the Troopers is because while the Troopers really were 1st rate for much of the decade from the mid 60's to the early 70's in Drums, Brass, Color Guard, they had quite a few show performances at the National Championships in the 60's, and pre DCI, ( VFW, American Legion, CYO, World Open, American Open, etc ) where their outstanding execution performance in M& M ( Marching ) was what put them over the top. They really could March in these years better than a lot of the Corps in their top tier placement range. One of their signature drill moves back then ( legacy fans here would know this ) was called " The Sunburst ", and typically it was executed flawlessly by their marchers by the time Championships rolled around. Whoever was teaching them M& M in these Championship winning years ( or Medal Years ) really knew how to get their Troopers Corps to excel particularly well in this caption. I want to say it was Jim Jones himself ( Troopers Founder )that was working the Corps at their practices to get them so clean and polished in M & M , but not entirely sure. It could have been others. But in any event, Man, could the Troopers march well in this era.
