The second part of the question, I believe, was about how we rate disabilities for service connection. We have what we call a rating schedule of disabilities, and it is broken down by parts of the body. It's also broken down by body systems.
I'm trying to think quickly of something to relate it to.
A veteran who has a knee condition or limitation of motion in their knee.... We have specific ratings that are related to each individual disability. It includes mental health disabilities as well as physical disabilities, impairments to vision—all those things are covered in that rating schedule. And it's based on the “whole body” theory; that was established many years ago. The percentage that is granted for the particular disability—for instance, a disability of the knee where you have limitation of motion—can be anywhere from 10% service connected up to 60% service connected, depending on the level of disability and the incapacitation.
