Given my experience with OSI, yes, because in many cases people don't start to exhibit an OSI until much later, and it could be triggered by any number of things. Based on medical professionals' experience, up to 25% of the serving military, both regular and reserve, could experience an OSI anywhere from minor to very severe conditions.
Again, that has to be done in pre-deployment and post-deployment screening, as well as pre-release screening. That's a pretty comprehensive program you're talking about.
