Russian Defence Ministry has signed a contract with the Akhmat group of Chechen Special Forces to assert its control over private armies fighting on its behalf in Ukraine.

The signing followed an order that all volunteer units should sign contracts by 1st of next month bringing them under the control of Defence Minister Sergei Shoigu.

In return, volunteer fighters would get the same benefits and protections as regular troops, including support for them and their families if they are wounded or killed.
