The Czech–Slovak Battlegroup[1] also, incorrectly, called the Czech–Slovak Battle Group[2] is an EU Battlegroup, led by the Czech Republic, in which Slovakia also participates.
The decision to form the CSB (Czech-Slovak Battlegroup), was made in 2005, and developed in 2006.[3] Between 2006 and 2008, the details of the chain of command were negotiated.[4] The group was active in 2009, and was at full preparedness from 1 July 2009 until 31 December 2009.[5]
The CSB consists of 2,600 soldiers, 2,200 of which are Czechs, and 400 Slovaks.[5] When at full preparedness, the CSB is capable of rapid deployment to anywhere within of Brussels.[4]
