A set of six "Tactical Whistle Commands" waterproof quick reference cards for you and your guys. Allows use of a whistle to signal and provide tactical command and control when radios inevitably fail.
 
Gives translations and mnemonics for "advance," "retreat," "rally," "shift left," and "shift right." For a deep dive on the tactical use of whistles, check out my blog post on the subject. 
 
3.5" x 2" (same as a business card) on 18mil waterproof plastic. Printed in the USA.
