e.g if player is on team”red” then Run script End)

local User = script:WaitForChild("Username")
local Rank = script:WaitForChild("Rank")
local Regiment = script:WaitForChild("Regiment")

game.Players.PlayerAdded:connect(function(Player)
	Player.CharacterAdded:connect(function(Character)
		spawn(function()
			wait(.8)
			local c = User:clone()
			local a = Rank:clone()
			local b = Regiment:clone()
			a.Adornee = Character:WaitForChild("Head")
			a.TextLabel.Text = Player:GetRoleInGroup(4887489)
			a.Enabled = true
			a.Parent = Character
			b.Adornee = Character:WaitForChild("Head")
			b.TextLabel.Text = Player:GetRoleInGroup(9959171)
			b.TextLabel.TextColor3 = (Player.TeamColor.Color)
			b.Enabled = true
			b.Parent = Character
            c.Adornee = Character:WaitForChild("Head")
			c.TextLabel.TextColor3 = (Player.TeamColor.Color)
			c.TextLabel.Text = Player.Name
			c.Enabled = true
			c.Parent = Character
			Character:WaitForChild('Humanoid').NameOcclusion = Enum.NameOcclusion.OccludeAll
			local h = Character.Head:Clone()
			local m = Instance.new('Model',Character)
			m.Name = 'NameTag'
			h.Parent = m
			Character.Head:WaitForChild('face'):Destroy()
			Character.Head.Transparency = 1
			local w = Instance.new('Weld',Character.Head)
			w.Part0, w.Part1 = Character.Head, h
		end)
	end)
end)

local User = script:WaitForChild("Username")
local Rank = script:WaitForChild("Rank")
local Regiment = script:WaitForChild("Regiment")

game.Players.PlayerAdded:connect(function(Player)
    Player.CharacterAdded:connect(function(Character)
        spawn(function()
            wait(.8)
		if player.Team.TeamColor == 'COLOR_WANTED' then -- sees if player is on the team. (forgot how to use teams but i think it something like this)
