It is necessary to study organizational culture to understand what happens in the organization and to find the answers to questions such as: Why do people behave in a certain way? Why do people decide in a certain way? If organizational culture is not recognized properly, its phenomena cannot be explained correctly. This research is indented to have a comparative study on three generations of the first, second, and third decade employees to a military organization. The views of these three generations are compared according to organizational culture values (regarding four organizational values  of 'mission oriented', 'change oriented', 'bureaucratic' and 'human oriented' organizational cultures). The results indicated that all components of the four organizational cultures exist at acceptable levels. However, some components of human oriented and change oriented culture need more consideration. The views of the subjects are significantly different with regard to change culture. It needs more attempt to improve the subjects viewpoint in this regard.
