A better depiction of the military culture was in 'An Officer and a Gentleman' from a few years ago. It demonstrates the values of the officer group. Each is its own segregated group. Movement from one level to another may be difficult. In-use values may not be as consistent as the expoused values of the organization.
Basic assumptions are much less visible.
What are the unconcious, reflex based, basic assumptions about the organization. If the Army is full integrated in its perspectives about itself, then all actions of the unit and its members will be consistent with no ambiguity. It does appear, however, when the issue of women in the military appears, that differentiation or fragmentation exists. As differentiation assumes that even though differing groups exist within the organization, they generally share their values, then it looks like this is not the proper descriptive term to use. We may well have this in Army-and perhaps in the entire military about this issue.
