If we place a rifle in a soldier's hands in a public place, he should be trained to use it to defend himself and have ammunition to do so. Therefore, if the task is ceremonial, give them swords.
If the threat level has increased and we wish for them to remain in the ceremonial role, then switch them from DEU to CADPAT with ballistic vest and helmet. When the threat reaches the level that a ceremonial task member requires ammunition then it is time to stand-down on the task.
