Soldiers from the US Army’s fourth infantry division's third Armoured Brigade Combat Team (ABCT) have crossed the border to arrive in Poland to enhance the security of the European country.

The army, integrated with the combined and joint air and naval forces of the US, has joined the regional forces of Poland.

As stated in a Eucom news release, US European Command commander and army general Curtis M. Scaparrotti said: “I would like to thank our allies and commend them on this historic moment.

“The European infrastructure and integrated support has enabled our force to rapidly be ready and postured should they need to deter Russian aggression.”

The 3,500 soldiers from US Army’s third ABCT have been deployed as part of rotations of the US troops and equipment in Europe.

"The European infrastructure and integrated support has enabled our force to rapidly be ready and postured should they need to deter Russian aggression."

The deployment helps strengthen the US Army’s ties with Nato allies.

US Department of Defense, Pentagon Press Secretary Peter Cook said: “This effort is part of our European Reassurance Initiative to maintain persistent, rotational presence of air, land, and sea forces in Central and Eastern Europe.”

The US troops will be stationed in Poland and other countries in the region on a rotating basis as part of Operation Atlantic Resolve (OAR).

In support of the OAR, multinational training and security cooperation activities are taking place in Estonia, Romania, Latvia, Lithuania, Poland, Bulgaria and Hungary.
