The VA just rated me 40% disabled for my back but nothing for my knee or heart, While in the Marines I had 1/3 of my knee cap taking out and later I had an Angina (heart ) attack also while in they rated the knee as service connected but 0 % the heart they said not service connected and 0% going to call a American Legion Officer the funny thing is I did not put anything down for my back the VA did that at the medical center
