Even though this has been in the game for months, I still see a lot of people who don't know about it. Often I'll hear in platoons "Oh many I thought Charlie squad's sunderer was Vanu!" or something similar. The default colors are perhaps not ideal. In order to change the color of any squad in a platoon, simply click on the squad name and it will bring up a color palette, allowing you to change the color to your preference. And that is a tip, from me, to you.
My charlie squad has been aqua since the day they let is change it. Much better. Grey is also an acceptable color
I'd like to point out that leaders and followers alike should refer to their squads as their names (alpha, bravo, ect). As some do change these from the default colors. Whether for personal reasons or vision issues.
