Why can't we take pictures of the recruits waiting in line?

What's your situation? Are you a soldier too? Or a reporter?

There are rules in the army. You may think it doesn't matter, and taking pictures is useless, but the army must be on high alert. Your photo will show the approximate number of recruits and reveal the number of troops. This is very dangerous, so please understand.
