I hope you're not implying that only combat vets are among the homeless or that combat is the only reason they are homeless.  There are hundreds of thousands of combat vets in this country.  There are also hundreds of thousands of vets who worked to support those who were in country.  Both are represented in various homeless populations throughout this country.  I, like many others, am a life member of the Veterans of Foreign Wars (VFW) - one of the many organizations dedicated to helping all Vets.  Homeless vets, whether combat or not, are one of the groups we help.  Most of us realize that homeless vets will not seek help until they are ready.  It is their choice.
