Grouping UI

So I have been working out how to do grouping as that will be very important.  So this is what I have worked up so far.  The first grouping is called a pod and will look like this for the three colors.

Basically there is 7 players involved with 1 player acting as lead.  I want the colors to reflect the amount of health that a player has, so if say half your group is frozen and 2 others are injured it would look like this.

The next size will be called a drit and will be comprised of 3 pods with an additional leader.  This one I will do in just green.

This takes 3 pods and puts them together with another leader for a total of 22 players involved.  The closer one is to the center the higher they are up in the chain of command.  I'll have to tweak the colors so it is clearer as to who is a higher rank, so for right now if they are brighter they are a leader of some sort.  I want to make it so only the leaders will see this formation, so basically the 4 players in the middle will see everyone, all of the other participants will only see the pod that they are a part of.  The last formation will be called a plat and will look like this which has been depicted in blue this time.

Again this takes 3 drits and attaches them to an additional leader for a total of 67 players.  Again only the four players in the middle will see this formation, which is the plat leader and the 3 drit leaders.  The pod leaders will only see the drit formation above, and all other participants still only see the pod that they are in.  Commanders would then have a special interface allowing them to see all of these formations in a given hexfield, or if they are in the main base everywhere in the game field.  Players will be able to identify group members by special icons or different colored text over the heads of group members.
