The Country Search criteria is now working properly and will enhance your searching capability. For example you can list a a unit and the country in which they were stationed and then under key word you could also put in another country to narrow your search.
For example one could put DERR as the unit, in 1978 - 1983 they were stationed in Germany, but went to Canada. By putting in those details with Canada as the key word one may well find images from their Exercise Medicine Hat.
