Once again, Special Operations troops in Afghanistan have run into problems with ROE (Rules of Engagement). This time around, Czech commandos were recently sent home because their ROE prevented them from doing what commandos do. In at least one case, Czech commandos were held back from an operation because it was considered too dangerous. In other situations, the Czechs opted out of an operation because they believed they did not have sufficient manpower.
There were also Arab commandos in Afghanistan, who eventually got pulled because of a growing list of restrictions, and fear that the presence of these elite troops be widely known. "Moslems fighting Moslems" is a hot button issue in the Islamic world, even though the Arab commandos were eager to go after al Qaeda, and other Arab terrorists known to be operating in Afghanistan.
