Jordan has one of the highest levels of peacekeeping troop contributions of all U.N. member states.

Summary of major troop contributions (over 400, 6 October 2008):

"It is absolutely essential that member nations of the U.N. step up and make those troop contributions," he said.

It has no army of its own and relies on voluntary troop contributions from member states.

In February 2006, the Netherlands decided to expand the troop contribution with an extra 1,400 soldiers.

Achieving this goal would depend, in part, on the number of foreign troop contributions.

No further troop contributions from other countries, other than perhaps a small contingent from Japan, are expected.

Thus, collectively, the 11 brigade replacement battalions represented troop contributions from 23 different infantry regiments.

Military necessity may have left no time to bargain with European allies over their troop contributions.

The precise troop contributions of allied members and other details still need to be worked out.
