The Engineer's emblem is the ram. It symbolizes the siege ram, of striking nature of ancient Greeks, which was used for violating the entrenchment. The ram, as a siege machine, was delivered by the Ancient Greeks and was initially used by the Romans and posterior by the Byzantines. In the book "Tactics" written by Leo VI, who is well known as Leo VI the Wise mentions that among the siege machines the so called ''seige rams'' is included. For the protection of the city walls, against the siege rams, packsaddles field by straw or sand were used.
The head of the ram, in various representations of the Ionians, were symbolizing the force and the power. The ram in ancient time was the symbol of freedom, due to the fact that Frixus and Elli mounted on a ram in their attempt to escape from inner Asia to the free and democratic Greece. The famous Golden Fleece, which Jason managed to seize with the help of Argonauts, and during his attempt to take it he killed the dreadful dragon, symbol of slavery, and he emancipated the daughter, was a Ram fleece.
Over the ram there is an epigram says ''as long with the words the acts come'', meaning immediate after a decision has been taken, it must be implemented, exactly how it is done in the operations of the Corps of Engineer.
This epigram expresses the military principle, which was adopted, preserved and delivered by the Ancient Greeks through Byzantine to the modern times. Leo VI the Wise mentioned the following in his essay "Tactics”
The primarily role of the Engineer in the theater of operation is the support of the friendly forces, in order to facilitate their mobility and increase their combat ability and in return to hinder the enemy’s mobility and reduce his combat ability.
