What is a squad leader?

I see things about the squad leader come up during games and I have heard of it before. What changes when you are it?

Solution 1:

There are a couple of things that differentiate a Squad Leader from a regular Squad Member.

Here are the differences:

• A Squad Leader is identified by a star marker next to his/her name.
• A Squad Leader has the ability to make a squad private or public to others.
• Squad Leaders are awarded points when marked objectives are either attacked or defended.
• On Hardcore mode, Squad Members can only spawn on the Squad Leader.
