Template:Special Rule: Chain of Command
Chain of Command. A force with the Chain of Command special rule may include one Lieutenant Commander character upgrade in a formation per full 1000 points. The Lieutenant Commander does not cost any points and may only be placed in formations that can take the Praetor upgrade. These free upgrades count towards a formations upgrade limit and cannot be placed in a formation with another Praetor upgrade. If you have more Lieutenant Commander upgrades available than valid formations then any excess upgrades are lost.
The negative effect of such a rigid command structure is that the loss of any unit with a CH upgrade in a formation will incur a blast marker on all friendly formations within 15cm of that formation.
