Captain Ishida Hisashi
No no no Captain Ishida's mind was a storm as he saw people dying around them, the dead trying to exact vague vengeance. But it was no time for despair, he knew. It was amazing how he could just shove all his pain into a corner of his mind and keep functioning, but then again being a doctor had given him a self-reflexive view of his own health and psychology, allowing him to do just that.
A thousand things were happening. Just a few days ago, he would never even entertain the idea of becoming the commanding officer of his squad - at least what remained of it - but then a horde of hundreds made a beeline for the caravan they were protecting, splintering his squad up and separating his shard of the squad from the Major who was in command of the whole squad. If he would have looked at himself now a few days ago, he wouldn't have believed the decisions he was capable of making. Sure, he'd headed groups of surgeons before and chaired meetings and conferences back then, but...
"Ichiro, take Sergeant Katsuo to the top floor!" The captain ordered in Japanese - Private First Class Ichiro could barely understand even simple English at all, "Sergeant, signal for an evacuation!" The young soldier, the liveliest of them all, returned to the SUV to help support Katsuo and get him to the top. With his bitten leg, he wouldn't be able to keep up with what might come anyway.
Just as he was about order the civilians to stay behind him, one of them hopped back over the SUV towards the horde of Kyonshi, talking about hearing the voices of another survivor. The Captain himself couldn't hear anything, but Sergeant Maiko confirmed the call for help. It was only a little bit later that he saw the source of the supposed voices. A stray woman who had been following them. "Wait!" The captain objected towards Malik's rash decision to rush forward, but his cries fell on death ears. "The rest of you, stay behind us!" He ordered everyone else.
The heroic man had hopped over the barricade, deftly weaving past the Kyonshi. "Maiko, defend him! Open fire! Bayonets!" The medical officer ordered rapidly in his native language. The animated dead fell around Malik as he sprinted for the woman, but most of them were Sergeant Maiko's work. The captain ran out of cartridges in his current magazine quickly, as he had neglected to replace it earlier with a fresh one. With most of the Kyonshi near the SUV dead, the two soldiers manning it decided to cross it and trail behind the foolhardy civilian, engaging the few that were left dangerously close to their makeshift wall with bayonets. In the melee, Hisashi did much better than his medic, killing several in a flurry of kicks, rifle butts and stabs.
Hundreds more were approaching, forming a wall of advancing death. Time was running out for the hero and the woman. "Maiko, grenade out!" The captain ordered, again in his native language. They both pulled out a grenade each and lobbed them at the feet of the crowd.
"Grenade!" Maiko shouted, in English, in the chaos. The five seconds fuse ensured that the grenades exploded only shortly after the wave of corpses had engulfed them in several layers of advancing bodies. The resultant explosion did not kill many - possibly only ten at the most due to the obscene amount of flesh - but it did maim a good number of them, and knocked even more off their feet. It had a domino effect, as a Kyonshi that was knocked off its feet would fall the one behind it and so on. The advance was stopped but slowly regaining momentum. It would buy them time.
