I know most of the drill commands but I am having a little trouble with the "Column right (left), MARCH" command. Can someone help me with how to perform this command? If you can find a video that would be great, video help would be the best.

It's rather simple actually. In a column right the command will be given and executed on the right foot. The person in the inner-most squad will execute a 90 degree angle at a pivit. The squads following will do the same mantaining a squad formation. Same goes for the column left.

I hope that helps and doesn't confuse you!

Additionally, on the column right, the pivot will be on the left foot, and vice versa for column left. Also, the column (usually four abreast), from front to rear is 'ranks', not 'squads', which are something else.

Thanks
