Yes.. it's true that a soldier should use everything at his disposal during fighting.
However.. during heavy fighting either in the jungle or in build-up areas, it is more handy to use the bayonet (fixed) if the enemy is too close to shoot... rather than hold another weapon (a knife etc) in one hand and the rifle in the other hand.

Of course, if special forces are sent to assassinate, then a gun with silencer or a good army knife will do well..
