(2) A training exercise will involve more than 900 British forces alongside NATO allies in Poland. According to the commanding officer, this military exercise will be observed by Russia and will give peace of mind to the host nation.
    (1)(2) By road, sea and rail, British sent trucks, troops and tanks to join 6,000 Poles, Germans and Canadians on the seven week training exercise, which looked at improving the way the allies worked together.
    A highlight was the demonstration for visiting senior officials of the fire power available to the allies. In Orzysz, armoured vehicles from the UK, Poland and Germany fired rockets and shells in a simulated attack, with red tracer fire ripping through the chilly north east wind.
    The first phase of the exercise took place on the other side of the country, before moving to North East Poland.
