Jimmy was not combative. He was strategic.
His strengths lay in the fact that he could wipe out armies with the aid of strategies, assuming he had enough time to prepare. His skills were set to stone recently, as he kept his people relatively safe from waves of enemies.
The situation they were in now was an exception, as his plans failed because the enemies used the bodies of their comrades to walk past the rocky barricade. Paired with the fact that half of the shooters were shitting themselves as soon as things started going wrong, one part of his general plan was destined to fail.
Within the depths of hell that this battle engulfed him in, he tried to stay calm. He was not a combative person, and he definitely wasn't built for it physically, as he was still a relatively young man, so he knew that he would not benefit from it if he decided to go apeshit, and fight people with his bare fists.
