The 150 combat troops are the first to arrive after Britain committed 3,300 troops to take over U.S. operations in Helmand Province, where militant activity is high.
The troops are tasked with general security operations, as well as protecting British engineers as they build a British base in Lashkar Gar, the provincial capital.
The remainder of the British contingent is to be deployed in the province over the coming months. The British troops are part of more than 3,000 British troops to be based in Helmand Province as part of a plan to expand the NATO-led International Security Assistance Force (ISAF) from 9,000 to about 16,000 troops this summer.
