They may have features resembling a variety of terrestial insect species, but these creatures are deadlier than anything bred on our world. Their armored exoskeleton is of particular intrest, and may provide insights towards the creation of an armor suit capable of activly damaging enemy forces as they engage in combat.
Presumably the name Chryssalid derives from assumptions made previously about the creature's unusual means of reproduction. Although rumors have long prevailed about the existence of zombies created as a byproduct of the Chryssalid gestation, recent reports seem to indicate that a new, equally disturbing means of propagating their species.
An inherently terrifying and unpleasant species to encounter by surprise, I can only admire our troops for their courage in dealing with the species known as "Chryssalid". Mirroring the general form of a common Arthropod, immediately noticeable is the sleek, armored exoskeleton protecting its segmented body. Of particular concern for our troops are the honed points of the Chryssalid's fangs and legs, capable of inflicting critical injuries on their own, they also allow for the creature's gruesome means of rapid reproduction in the field.
Although Central Officer Bradford insists that he witnessed a different, equally invasive means of Chryssalid gestation during the earliest days of the war, there is no evidence that such attacks still occur today. Unfortunately, from what he's described, I would say the aliens have actually evolved the process into a more efficient, and deadly, solution. The Chryssalids we see today inject a venom that immediately begins softening the victim's internal organs, preparing the subject to serve as both the material for a gestation cocoon, and as a ready supply of nutrients for the Chryssalid young. Should the victim fail to receive medical support and expire, the cocoon will form shortly thereafter. Assuming the cocoon is not destroyed during the initial gestation period, we can expect up to three Chryssalid young to emerge after an impressively short period of growth.
Recent reports from the field indicate some form of "burrowing" behavior, perhaps another evolution of past techniques, in this case likely for defensive purposes. Our troops would be well-advised to watch where they step in the future. R. Tygan
