This list of ISAF Major Force Units constrained with national caveats by Lead and Supporting ISAF coalition TCNs was created based on the caveat information I gathered and compiled during the course of my doctoral research on the ISAF security assistance mission between 2008-2014, especially the data relating to the specific and various constraints imposed by caveat-imposing Troop Contributing Nations (TCNs) within the ISAF coalition on their deployed national armed forces, over the period of more than a decade of warfare in Afghanistan between December 2001 – December 2012.
