Welcome to the War: A Terran Common Union novel

It was supposed to be a training exercise... The Terran Common Union is at war with the reptilian Draghan race. When the green troops of the Second Brigade of the newly-raised Yillian Fourth Division drop out of hyperspace in the Vangna system, they are thrust straight into the conflict. Forced to abandon ship, their jungle training manoeuvres become a desperate fight for survival in a hostile environment which could not be more different from the terraformed farming world they call home. Will the inexperienced conscripts be able to last until help arrives? And will the support they pray for come without an ulterior motive...?
