Giving certain teams different weapons?

The script is as follows:

local ReplicatedHolder = game:GetService("ReplicatedStorage");
local TeamsHolder = game:GetService("Teams");

-- // Teams that can be found

local RedTeam = TeamsHolder:WaitForChild("Red Team");
local BlueTeam = TeamsHolder:WaitForChild("Blue Team");


-- // Weapons that are held in the ReplicatedStorage

local Weapon1 = ReplicatedHolder:WaitForChild("Weapon1");
local Weapon2 = ReplicatedHolder:WaitForChild("Weapon2");

-- // Events

game.Players.PlayerAdded:Connect(function(player)  -- Gives the weapon when the player joins the game.
    local Bp = player:WaitForChild("Backpack");
    print(player.Name .."'s Backpack has been loaded!");

    if player.Team.Name == "Blue Team" then
        local ClonedWeapon1 = Weapon1:Clone();
        ClonedWeapon1.Parent = Bp;
    end 

    if player.Team.Name == "Red Team" then
        local ClonedWeapon2 = Weapon2:Clone();
        ClonedWeapon2.Parent = Bp;
    end
    player.CharacterAdded:Connect(function(character) -- Gives the weapon when the player respawns in-game.
        local BackpackRespawn = player:WaitForChild("Backpack");

        if player.Team.Name == "Blue Team" then -- If the player's team is "Blue Team" then gives Weapon1, from ReplicatedStorage.
            local ClonedWeapon1 = Weapon1:Clone();
            ClonedWeapon1.Parent = BackpackRespawn;
        end

        if player.Team.Name == "Red Team" then -- If the player's team is "Red Team" then gives Weapon2, from ReplicatedStorage.
            local ClonedWeapon2 = Weapon2:Clone();
            ClonedWeapon2.Parent = BackpackRespawn;
        end
    end)    
end)

Tried to break it down in both :PlayerAdded() and :CharacterAdded()events. You basically give them a weapon once they join the game & later on you give them the weapon once they respawn depending on the team they are at.

Hope this helps you!

I'm aware that I have given you the whole script as a request, but hope you learn from it, check the Roblox:API more often!
