Ukrainian soldiers would "have a bad time" if they used American fighting doctrine against Russia.
He said that NATO training for Ukraine's troops includes discipline, which is unnecessary given the stakes.
Jackie also pushed back against the idea that Ukraine should rigidly follow NATO standard training, and even argued that such a thing doesn't really exist.
"I keep hearing 'NATO standard' getting thrown around, and 'NATO standard training' or 'NATO standard doctrine'," he said, adding: "The Polish infantry does not fight the same way as the American infantry."
To those training Ukrainians, he said, simply: "Don't get worked up about the procedures and the organizational stuff and ribbons and medals."
