NOTE: I made this on a game that includes the altered sprites from the Miranda Class (In the thread called 'Help with Importing ships'), I am not sure if it works without those altered sprite files.

//*********************************************************************************************************
Open 'Gui_Global' (C:\Program Files\Activision\Star Trek Armada II Fleet Operations 3.0\Data\Sprites) and look for: 

all_alliedrepairw5	wireframe10	96	96	96	96		#		

add beneath it:

fed_commandw5	wireframetyler	288	192	96	96		#				

//*********************************************************************************************************
then find:

b_fed_ambassador	federationbuttons04	258	3	80	80		#	4	1

and add beneath it:

b_fed_command	federationbuttonstyler	3	88	80	80		#	1	2
