Nothing new. DoD has long tried to force disabled veterans onto the VA's budget rather than carry them on Defense rolls.
If a service member is retired on disability by the military, they pay for it. If they can seperate the service member and refer them to the Department of Veterans Affairs and are deemed disabled then those costs are borne by the VA.
This is especially tough on first-termers who may not understand the distinction and then have to go through the VA disability claim process. The Disabled American Veterans is probably the best resource to help in applying for a service-connected disability. The American Legion is also good, but not as focused on claims processing.
