Also, in the Localization/#dlg_mp.lng file, in there you will find a section

{"groundcontrol" "Ground Control"}
{"groundcontrol"
{"objective" "To win, capture and hold more than a half of all the terrain."}
}
}
{"army"
{"ger" "Germany"}
{"rus" "Soviet Union"}
{"usa" "USA"}
{"jap" "Japan"}
{"can" "72nd Canadian"}
{"eng" "United Kingdom"}
}
{"stage"
{"lobby" "In lobby"}
{"session" "Starting the game"}
{"game" "Playing the game"}
{"zone" "In lobby"}
{"gslobby" "Main room"}
{"gssession" "Game room"}

you will have to add your nation into the "army" section

"gr" for the first part and then the 2nd "72nd Canadian", that part is whatever you wish the name to be displayed as in Multiplayer.
