Active writing has the form subject +verb+object. eg The colonel shot the deserter We are told who did the action (shoot). The opposite to this is passive writing which has the form object + verb. eg The deserter was shot. We don't know who did the action shoot. This applies to army writing or any kind of writing, active writing would always tell you who did the action of the verb

Technical writing can read like its writer knows more than the reader. This denies the reader the dignity the reader has earned. To avoid this, a technical writer can write as though the writer sits at the reader's elbow offering kind guidance. The writer can write in the third-person, in the present tense and in an active voice. This can help the reader preserve his or her dignity.
