Just got that email too. I can't find my damn VA health card now. I've never used it and I think I lost it in a move.
Call your VA rep and they'll tell ya where ya can get a new card. I've got to get a new card also at the end of the month,our clinic 50 miles away only does them once a month.
The new card for which you'll need has your picture,an identification #,branch of service printed on it. This is the card you'll need to access military installations.
