NATO is completing a first testing of its new force created to face new challenges from Russia.

Some 150 soldiers from the Czech army's 43rd airborne battalion have been training to be ready for deployment within 48 hours "as NATO reevaluates the risks," Maj. Gen. Jiri Baloun said Thursday. The previous NATO standard times for that were between 10 and 80 days, Baloun said.

In the Netherlands, 900 German and 200 Dutch soldiers have been doing the same. The units will be moved for further trials to Poland in June while some 25,000 NATO troops will complete the exercise of the new force in Italy, Portugal and Spain in October and November.

The units belong to NATO's new Very High Readiness Joint Task Force.
