Sound advice for all organizations, not just the military. From the Harvard Business Review:
In the military, a poorly formatted email may be the difference between mission accomplished and mission failure. During my active duty service, I learned how to structure emails to maximize a mission’s chances for success. Since returning from duty, I have applied these lessons to emails that I write for my corporate job, and my missives have consequently become crisper and cleaner, eliciting quicker and higher-quality responses from colleagues and clients.
