I remember cadets getting into trouble by putting a combination lock on their lock-box. Was it called a bootie box? And then leaving the combination sticker on the other side since someone could then easily open the lock.

At the time, I had the thought, from a security perspective, of the following.

What if I bought two combination locks (with different combinations) and carefully switched the stickers? I assumed that I would still get in trouble even though the reasoning of allowing someone to easily open the combination lock was no longer valid. So it just remained a thought.

In military operations, deception (or cleverness) against the enemy is supposed to be valued, but here it would just get someone into trouble.
