According to a series of 3 articles in the Washington Post of 1998, the US military is involved in training foreign armies in "at least 110 countries". These operations, called Joint Combined Exchange Training (JCET's) are free not only from civilian oversight, but are often hidden from other US Government departments. Some of the armies named were from repressive regimes; it is even likely that US Forces trained some of the units that committed genocide in Rwanda.
