British troops have been practising storming into action in Poland.
2nd Battalion The Mercian Regiment, from Dale Barracks in Chester, were caught on camera during the multinational training exercise.
They were conducting operations in built up areas on Exercise Anakonda in Poland.
The regiment is training alongside Polish, American, Canadian and Turkish allies.
They're in Wedrzyn, in Northwest Poland, and have been training hard with NATO allies in preparation for a brigade attack.
Exercise Anakonda is being used to train multiple nations together to ensure they are able to travel anywhere in the world and work with each other to fulfil common security interests.
This exercise helps to demonstrate the UK's commitment to the objectives of the Wales NATO summit, and helps troops work towards the goals of the Warsaw summit coming in July.
Britain has committed a battlegroup to the current Spanish led rotations of the Very High Readiness Joint Task Force (VJTF), and is due to take the lead in 2017, where it will contribute 3,000 personnel.
