The most of this formations are self explaining, and like always don't walk to close to your squad mates, a distance between 3 and 5 meters is OK, but if you have more space why not use it...
lets start her you see what the different Colors mean, on my great paintings

Staggered
not a lot to say to this one.
yellow and red covering the front, the other guys cover the right and the left of your squad, brown also covers the back.

Then we have the 2 L formations.
With the L formation, you have to Speer tips, one of them is covering the SL and the medic.
L Right

L Left

and my 2 favorites
The Y formation, is good for urban areas.

Lets say you have to retreat backwards, red throws smoke (if needed)
yellow fires on the enemy ( the best is 2 shots break 2 shots break and so on) after yellow fired a couple of rounds, he moves back to the end of the formation, now Green is in the front, Green covers red, while red moves to the end of the formation, and so on and on till you are all in cover, if you retreat this way, you will always have suppressing fire on the enemy, and you have plenty of time to reload your weapon.
Of course you will go for the nearest cover, but I did take backwards as an example.
And if times get hard there is the Hedgehog
fire power to all directions for the last stand, or just to set a rally.

I hope it wasn't to bad, and sorry for not writing more about the other formations, but I think it should be clear, if not feel free to ask,maybe I will bring up some more, but I am not sure yet...
dose any one of you have formations to share, and when do you use them?
