If you are the Big brother of a Four Men Prayer group, you are also a Corporal in the God's Marines.  However, if you are not a big brother you can still attain higher rankings by helping other groups to be formed.  If you help another Four Men prayer group to be formed you will be the Father/2nd Lieutenant of that group.  It will be your job to reach out to the Corporal/Big brother every six months to see how he is doing with his group.  

Other Ranks attainable:
1st Lieutenant has five groups under his direct supervision.
Captain has 10 groups
Major has 20 groups
Lt. Colonel 30 groups
Colonel 50 groups
Brig General 100 groups
Major General 250 groups
Lt. General 500 groups
General/Commandant All the Groups 

I cannot wait to make General.  I got a long way to go.  We all can do this, let us raise up an Army of God's Marines and help convert the whole world, one paralytic at a time! 
God Bless you, your brother, Brian
