For the 2nd time, Ben showed his vastly improved war acumen.
The others in the strategy room including Rex were intelligent enough to think of this, but it was the speed at which his brain worked to quickly think of this that set Ben apart from the others as a better war strategist.
Ben was chubby, direct, a terrible womanizer, and even sometimes knuckle-headed but when he was motivated to learn something, he gave his all to it.
During his short time spent in the Great Myriad Metal Shelter, he attended military classes of the Big-bone family on war strategies and responses.
Back then when he thought about his 2 childhood friends, from the wars that went on in the Great Shelter, he knew that strength alone did not cut it to fight and save them, he also needed a proper war mind to achieve great things.
After graduating from the academy of the Big-bone family, his decision was to go seek the patriarch's permission to go out and build his own army.
