The routine ones are at recruitment initially, with the routinely scheduled periodic health assessments that occur regularly, before every deployment overseas, after every deployment overseas with a very detailed evaluation, during subsequent periodic health assessments, and again at release.
In addition, for every routine assessment or during care for a runny nose or whatever brings someone in contact with the health system, there are also usually informal evaluations. All our clinicians are sensitized to do that, right down to the level of the medical technician.
