Marginal Operation manga volume 14 features story by Yuri Shibamura and art by Daisuke Kimura.

Going on the offensive...

With the Chinese Army presenting an overwhelming difference in firepower to his own forces, Arata employs guerrilla tactics to successfully take out a key refueling base. However, this enrages the Chinese Army more than expected, leading to an air strike against Camp Hakim in retaliation. With the Burmese Army still disorganized and his sponsors unwilling to lend further aid, the only person Arata can rely on to get them out of this mess is himself.
