'Why are all veterans on disability'

I hear Caleb say this three times I think now and he referred to the surprise that he perceives each veteran on his show to be on disability. He then projects that not everyone can be on disability.. why not?

Makes more sense to me that anyone that works for the US military becomes disabled then assuming the common denominator is people lying about being disabled.

Appreciate US has a rich culture of prioritising and culturally valuing your employees of airforce, military, marines etc. so happy for this to be the reason I don't understand his scecity when it comes to disability.
