The main goal of this paper is to conduct descriptive survey on an ergonomics assessment of driver's seat of T72 tank. The basic questions for this research are (i) To what extent the soviet fabricated tank driver's seat is comfortable to Ethiopia army, (ii) Is there significant different between the body size dimension of soviet and Ethiopian army, and (iii) The Ethiopian military derivers have awareness of the comfort.

It is necessary to define the drivers’ space and seat dimensions by considering the size of the average people according to their body dimensions.

So the question of the correct ergonomically design and analysis of the driver seat especially in terms of comfort is mandatory so due to this fact, study anthropometric of driver's seat is very important. In Ethiopia T-72 tanks are the most important weapons that give a strong support to the ground force in the battle field. For this reason anthropometric plays a great rule in the world in design of products. In the world it is difficult to design in terms of average dimension.
