Just don't right click enemy troops, use the stop command instead and they won't dance.
With DP-28s I'd say they are one of the most cost-efficient squads in the game due to really good vet. They also have amazing utility in the form of second best nade and button vehicle.
They still will.
Its easier to control them when there is absolutely no cover around, but put some yellow in the vicinity and they will go batshit crazy.
They have good stats and scaling, they simply suffer from retarded AI.
