Abstract
We examine the virtues and difficulties of the attempts to construct realistic four-dimensional models from a gauge theory based onE 8 and defined in ten dimensions. The four-dimensional theories are obtained using the coset space dimensional reduction scheme. Some of our points and in particular the proposed mechanism for supersymmetry breaking might be useful in other dimensional reduction schemes.
