So... are there military patches for non-military individuals? I believe so, as evidenced by the Defenders of Freedom - I Stand Beside Them patch at The Cheap Place. Weather this one was specifically designed for non-military personnel or not, those of us who never served but fully support our military could wear this patch proudly. And like some of the other military patches that are similarly shaped, this one is intended to be attached to the front of a baseball cap.
What I like most about this patch is that it perfectly expresses my sentiments toward the military. I stand behind them 100% -- even though I never served. Although it's not as though I wasn't willing to serve; I was rejected by all four branches because of a childhood heart condition. Nonetheless, I have friends and family members who are either currently serving, or have served in the past, and I'm proud to be associated with them and to lend moral support and encouragement whenever I can.
If you're in a similar position why not consider showing your support by purchasing some of these patches and distributing them among your other non-military friends. Together you could form your own brigade with the purpose of welcoming soldiers home and finding ways to bless and support them. The patches are very inexpensive and can be shipped right to your door free of charge, if your order is $10.00 or more and you live in the U.S.
