Final answer:
In fire suppression, each drop of a progressive hose lay usually consists of lengths of fire hose and necessary firefighting tools and fittings.
Step-by-step explanation:
Since the question appears to be related to fire suppression and management techniques, a "Smokey Pack" likely refers to a firefighter's method or tool used in containing wildland fires. A progressive hose lay is a fire suppression technique where hoses are laid out from the water source towards the fire, extending as the fire is fought. Each drop of a hose lay would typically consist of lengths of fire hose along with necessary tools and fittings required to combat the fire. These may include nozzles, wyes, reducers, and other firefighting tools. Moreover, each drop might have a specific length of hose designated by the fire department's protocol, which could be based on the scarcity of water, the type of terrain, or the intensity of the fire.
