Further_Notation: Due to the inclement weather of Traus 77.14, fire warriors have been issued with Hostile Environs Capes. Made of unknown fibres, this cape is a dense, heavy and hardwearing cloth that is completely waterproof. The cape can be wrapped around the warrior completely, only leaving the head and shoulder guard exposed, and is quite warm, ideal for the harsh winters on Traus (Personal_Note:Curse this cloak, may all Xenos freeze to death and save us the munitions). Closer examination of the cape, reveals that when stationary, it will discolor, mimicking the local environment. If let alone for 30.02 minutes, the cloak becomes indistinguishable from it's locale.
This curiosity may explain why the Tau are so efficient at holding ++CLASSIFIED++ and rolling advancements.
Why then leave the head and shoulder exposed?
AMMENDED_NOTES:The Traus 77.14 conflict, as I understand it, has had little military imperial involvement. Traus is a despicably cold planet with little value beyond the meagre mineral wealth rogue trader's can mine from it(PLANETARY_TITHE///TERTIARY.///?///-SEE_HTuPPx). It came as a great surprise then, that a Tau War fleet was discovered in system. What little pict evidence we have, came as courtesy of mining servitors, or servo skulls abandoned by the populace.
