I agree with the others. The worst choice would be five (5). If you say the military uses this option, it could be because they are overly cautious and want to avoid errors at all cost (excessive here). Spelling out numbers vs. using numerals is a preference not a rule.

Please don't change all the introductions they look fine the way they are.
