My knowledge of the Spartans is limited to a handful of awesomely bad action movies that are awesome.
When the soldiers fight together, the shield of one dude protects the person next to him–and this is repeated all they way down the line. The individuals band together and become a single entity: united and loyal to one another.
A unified team works together. Everyone is on the same page and moving forward together. Strategic unity means everyone is working toward the same goals and objectives.
A loyal team cares about the welfare of others on the team. When one is hurting, the others notice and respond. When one is successful, everyone is excited as if it was his or her victory. Competition is never more than anything other than a joke because loyalty overcomes insecurity. Loyalty stands up to complaints and gossip, encouraging the outsider to talk to the source of their frustration.
QUESTION: why do you think unity and loyalty are important? What happens when these values are missing from a team?
