DarkRP group chat

How would I add another team called** TEAM_RUSSIAN and TEAM_RUSSIANBOSS** to another group for the chat.
[lua] elseif string.sub(string.lower(text), 1, 3) == "/g " or GroupChat then
HearMode = “group chat”
local t = LocalPlayer():Team()
playercolors = {}
if t == TEAM_POLICE or t == TEAM_CHIEF or t == TEAM_MAYOR or t == TEAM_SWAT then
for k, v in pairs(player.GetAll()) do
if v ~= LocalPlayer() then
local vt = v:Team()
if vt == TEAM_POLICE or vt == TEAM_CHIEF or vt == TEAM_MAYOR or vt == TEAM_SWAT then table.insert(playercolors, v) end
end
end
elseif t == TEAM_MOB or t == TEAM_GANG then
for k, v in pairs(player.GetAll()) do
if v ~= LocalPlayer() then
local vt = v:Team()
if vt == TEAM_MOB or vt == TEAM_GANG then table.insert(playercolors, v) end
end
end
end[/lua]

Anyone?
