 One of our company is deploying the exercise fields with main tasks to conduct offense operation. Clear the down is cure all areas around. We've got the Bulgarian company here and we're doing simple blocking and tackling infantry tasks on the ground. So interoperability is not a big problem. It's working those small tactical pieces to put it all together so that we're truly interoperable on the ground. A specially constructed village right here offers us great potential for different scenarios and cooperation with different tactics employed by different tensions.
