From the very moment Napoléon Bonaparte took power as First Consul in the coup of 18 Brumaire, he was feared by his rivals, and keenly supported by the army.
The violence of the coup d'état had already caused disquiet, and the consuls had access to an impressive Consular Guard.
[1] From 1866, Napoleon III wanted to establish a military reserve comparable to the Prussian Landwehr.
The increase in conscripts allowed service in the active army to be reduced to two years whilst still maintaining its strength.
The Army operational reserve is about 60% headquarters/staff specialists and 40% sub-unit reservists (company, battery, squadron, drill).
