www.classmates.com also has a listing of 1/32 service members; and www.military.com (http://www.military.com/Page/0,12170,1-OO-0,00.htm) has a buddy finder. You do have to register with both to become listed. This is a free service, but the classmates.com has a fee based feature for something like $30.00 annually, but the fee based membership is not required to become listed.
The military.com website also has a page dedicated to the 1/32nd. Again you have to register to obtain access to the site. They only have something like only 27 former members of the 1/32nd FA! They have a buddy finder with e-mail links to those persons (if they have e-mail). They have obtained their database info from the DoD.
