Below is a possible Egyptian civilization emblem, the Eye of Horus. It was a sacred symbol throughout ancient Egyptian history, and represented health and protection. The background shield color yellow/gold represents an eternal or imperishable quality, often associated with the sun, and the eye's blue color represents creation or rebirth, often associated with the sky or water.
Below is a representation of a (conventional) Middle Kingdom spearman, with variations of bulls' hide shield covers. The appearance of this unit and his equipment is based on the Cairo Museum's wooden soldier models from the tomb of Mesehti, an 11th dynasty official.
