A formal complaint must be made in writing and submitted directly to the commanding officer?

Avoid using 1st person and 2nd person. Often, using these points of view causes writing to become weak, and unconvincing.

such as letters to the principal or the mayor. XD

Well, if its writing, then i think its..Mesopotamian king... um... maybe its Hammurabi.

Expository writing is a formal writing. It's purpose is to explain, inform, describe, or define what the authors subject.

In most states you need an acceptable record and a high school diploma or GED.
