How to do the Radioman
As a Radioman you'll be carrying with you a small radio backpack, this radio it's not only for aesthetic but actually has a purpose, with said radio you'll be able to call in artillery support (only if there is available artillery) and armoured support (only if there is ally armor on the battlefield) to a specified location, to call in artillery support you'll need to give the right coordinated to the artillery, be careful as giving them wrong coordinates will make the artillery miss their mark, calling in armoured support instead it's easier and cannot be failed. (note the Squad leader can mark for your objective he wishes you to call support in, however as the Radioman you have the choose to approve or decline the squad leader request, in chase you believe he might have mark the wrong target)
