An Expert in Demand
The following is pulled from pg 18 of Cry Havoc 3 Gaming Aid.
Becoming a siege engineer requires great intelligence, patience, and loads of courage. There are very few of them and their secrets are highly coveted.
An Expert in Demand: One siege engineer can be deployed for every even incomplete 200 A. P. of war machines (including Allied ones) and their servants in the army when it is built. He is considered to be a servant of all the war machines in his army.
When operating a machine, a siege engineer of the Guild of Architects is always considered to be a servant, never a substitute. He must nevertheless meet the conditions imposed by the machine.
He counts as two regular servants when determining the penalties bound to missing crew-members.
