GRgeo, your question to Dragon's question comes off a bit condescending. Please, try to use a different tone when responding to a legitimate question.
That said, Dragon62 does raise a valid point. Survival Training is a skill gained through training and equipment. The Venusian Rangers and the Venusian Ranger Kaptain have Survival Training and cool armor suits. The Venusian Ranger Marshall appears to have the same armor, and, theoretically, has had the same training that the other rangers have had, fluff-wise.
Strategic Insight, on the other hand, is a skill that a model that represents a higher officer might have. It is not a skill that lower level troops would possess, as it is a skill that is, generally, learned through experience and training and, when exercised properly, can result in being promoted from the rank and file to the position of Marshall.
While I do not, yet, know the answer, Dragon, I will try to find it for you.
