Im not sure how the initial contact was made, but army personnel did come to their house. My GD was also in the army, and shes pretty sharp, so it would take some doing to fool her. When i posted this, i didn’t know the army had come to her house.
In the meantime, these suggestions will help them a lot.
Army dudes in uniform arrived at the house to discuss collecting money? Baloney. The Army does not send folks to vets houses, they mail them a letter. Better dig deeply into this. Your State Representative has a military staffer- call them and give them the details. Call DFAS (Defense Finance and Acctng Service in Louisville KY- they can be searched for online. Does not pass the smell test, this one.
There are only two events that prompt uniformed members to call on a home- death of a service member on duty and Criminal Investigations Command- and those guys come in suits.
