This story picks up immediately after where Ch. 04 leaves off. You really should read it first... actually you should start with Ch. 01, and read the whole series. This would all make a bit more sense. If you need a face for Trooper Marlena Fuentes, it'd be Christian Serratos, Rosita from "The Walking Dead".
=================================
Trooper Marlena Fuentes ran gasping through the wheat field as fast as her legs and lungs allowed, the burning pain of fatigued drowned out by the terror of what was certainly behind her. Her teammate was certainly dead, and she knew that her own fate would be far worse if she was captured by the Intai Juhen. Despite the blind panic which propelled her forward, she'd had the presence of mind to hang onto her rifle. Marlena's helmet had come off her head, and her shoulder-length hair whipped around in the dry wind as she continued a fruitless race towards the illusory safety of the farmstead and small grove of trees which lay in the distance. If she could make it there she might find a radio, or at least a hiding place.
A half mile behind her, the Intai Juhen combat drone loped ponderously along Marlena's route. The combat drone was a mass of chitin armor, blades, and countless organic weapons the size of a small car. Oriented a bit like a centaur, the combat drone had four large legs to propel it across the field. Several arms hung folded on its thorax, along with numerous small protuberances housing various organic weapons and smaller, more specialized drones.
The converted human male warrior, his eye sockets now filled with twitching gray sensory organs, trailed behind to keep watch for possible ambush by other humans. Though they were small and fragile, the humans were tenacious fighters on their homeworlds. Likewise, the humans here had begun to employ powerful chemical slugthrowers capable of piercing even the thick armor or the combat drone on a lucky shot.
Humans were faster over short distances, but the combat drone was in no hurry. The female human's trail was clear within the wheat field and her chemical signature was easy to follow. The Intai Juhen Foremost Caste had decided that female human fighters made especially good playthings for the arenas, and should be captured alive and intact whenever possible. The combat drone would have to capture here and bring her in alive, her psyche untainted by the narcotic effects of the Seducers and Harvester. These drones were designed specifically to incapacitate females using their own orgasmic responses, leaving them placid and responsive to the psychic commands of the Intai Juhen. The combat drone faced a more complicated task than subduing noncombatants, but it knew that it would be rewarded; the combat drone able to savor the terrified psychic emissions of the female human for the entire time until she was delivered to the primary lair for processing. Knowing this, the combat drone accelerated its pace.
