Become a Plank Owner!

On a fighting ship, a "plank owner" is someone who was part of the crew when the ship first commissioned. If you are one of the first 1000 to join us you will be a "Plank Owner" at WMI for life, receive a special serial-numbered certificate to prove you were here at the beginning!

WMI Member Courses

In addition to unlimited access to the Pacific Air War course and all other upcoming WMI courses, the first 1000 to join (plank owners) will also get complimentary access to the Special Tactics Squad-Level Infantry Rural Combat Course.
