If no snipers are recruits and all recruits wear red berets, which statement must be true?

A unit deploys only when conditions A and B are both met. Condition A is met. What happens?

Both A and B must be satisfied; meeting only A is insufficient for deployment.

Either the convoy travels by road or by air. It does not travel by air. What follows?
