You can be a valid Apache Attack Helicopter if you want to be. Nobody else gets to decide whether that’s valid except you. You might confuse or even mislead some people, you’ll have to be prepared for that, but before you consider whether it even matters that some people get confused or misled, you should consider why it’s any of their business in the first place, because it probably isn’t. If it is, then by all means, check whether it’s valid with them, not us.
