Squads can be classified based on their function or purpose, such as infantry squad, fire team squad, or special operations squad. They can also be classified by size, with typical squads consisting of 8-12 members, depending on the military branch and country. Communication, leadership structure, and tactical roles within the squad also play a role in how they are classified.
The only extant cephalopod that produces an external shell is the chambered nautilus. The shells produced by squid and cuttlefish are internal.
