Research report about "odd behaviour":
Commander,
We have spent the past few weeks investigating these strange occurrences in our Containment unit, and we believe we've formulated a theory that may begin to explain the aliens' newfound intelligence.
It seems that we were off in our preliminary appraisal of how the alien intellect works. We first believed them to be autonomously operating individuals, in the same way humans are, though with superior communications and team tactics. However, our lab experiments and an intense review of battlefield footage now seem to contradict that hypothesis.
In our video records, we have often seen the aliens seeking cover, coordinating their fire, working as a team even though they carry no obvious communications equipment. However, when we captured a few live specimens in our Containment unit, they never displayed anything above the level of animal instinct. This seems incongruous with the evidence we have; large, well-developed brain structures and a proven knowledge of combat tactics.
We sought to reconcile these ideas in a new hypothesis, and our experiments have begun to produce tangible results. The new specimens certainly are responsible for the strange behaviour we've observed, but we originally assumed that they were officers of some type under colour of authority. We now believe that theory to also be wrong. Our experiments prove that when the aliens are allowed to congregate, with or without the suspected 'officers', they become significantly more active and sophisticated. When they are separated from each other for a large enough distance, they revert back to their basic states. The conclusion is obvious. There is some kind of communal force binding these creatures together.
A string of new theories has emerged. The most likely explanation is in the alien brain. There are several species of alien, all of which meet the physiological requirements for a sentient species, but they show little to no brainwave activity of their own. This implies the presence of some kind of shared or distributed thought between them, a hive mind that grows more intelligent as it grows in numbers. We're not sure how it's possible for this hive mind to cross species boundaries; it's obvious that the different alien races originated on different worlds, with vastly divergent evolutionary paths, and some species appear to have been around far longer than others. However, given the aliens' advanced technology, the 'how' is less of an enigma than the 'why'.
These new findings also seem to suggest that specimens down on Earth are cut off from the source of their intelligence. While this may be an important advantage for PHALANX forces, it also brings up threats we had not yet considered. Our research into alien physiology has established that isolated specimens cannot survive very long in our environment, and behave with little enough intelligence while they're on the surface; but if a large enough number is allowed to escape and coordinate with each other -- or with alien sympathisers on Earth -- we could be looking at a serious infiltration risk.
With several specimens on hand, their intelligence now seems to be approaching the human level. If we can create a suitable translation device or common language, we believe we may finally be able to establish communications with aliens in PHALANX captivity. Perhaps some of our linguists or psychology experts could form a dialogue. This is an avenue of inquiry that we cannot afford to ignore.
Of course, if such experiments were to be approved by the Base Commander, I assure you that my team would take full precautions. Nothing is more important to us than the lives of our men and the security of our facilities.
Sincerely,
Dr. Connor
