Bayonets are more likely to figure in parades and inspections than any realistic training for combat. Realization that the awkwardness of stylized bayonet fighting movements is outdated is far from new. In the 1890s, General Evelyn Wood, VC, remarked that the bayonet training of the day was "more suitable for a Music Hall than for training men to fight."
There is no perfect close quarter weapon because attack and defence are very individualistic. The bayonet has to be one of least efficient close quarter weapon.Compare this stylized training approach to the fact that soldiers will often "club" their weapon, swinging the mass of the butt, the barrel as handle, because it was more effective.
