Practical example how to get soldiers to choose for the same option and to act as 1.
We have candybars named Nuts and Mars.
A sergeant had a bag full of Nuts candybars.
He had the platoon in front of him and said to them, "time to choose, do you want a Mars or a Nuts?"
About 60% of them were smart and choose for the Nuts, the others liked the Mars more.
However, Mars is Dutch for marching.
So he gave the men who asked for the Nuts the candybars.
The others had to take their weapons and gear and went out for a 20 km walk
Needless to say some of them were very angry about the others.
