Boom

One of Rudra's biggest strengths was making his enemies dance on his fingertips.

Through his two lifetimes he had played every role in the military hierarchy. 

In his first life he had been the cannon fodder, he had been the useless team member and eventually he had been the team leader.

He had participated in guild wars as a soldier, as a captain and once even as a division leader, hence he knew exactly how the lower echelons of the military world worked and how tightly were the orders of the superiors enforced. 

He knew how fragile morale was within g troops and how plans and formations went to hell once something started to go wrong and it was exactly this knowledge of human behaviour that allowed Rudra to become the strongest guild master in his second lifetime.
