How to script a npc that does not shoot your team only the enemy?

my script:

local figure = script.Parent
local Tool = script.Parent.PaintballGun
local reload = .5

function modechange()
    local mode = figure.mode
    if mode.Value == 1 then reload = .5
    elseif mode.Value == 2 then reload = 5
    elseif mode.Value == 3 then reload = 1.5
    elseif mode.Value == 4 then reload = 10 end
end

function findNearestTorso()
    local targetTorso = nil
    local distance = 500
    local list = game.Workspace:children()
    for i = 1, #list do
        local listTorso = list[i]:FindFirstChild("Torso")
        if listTorso ~= nil and list[i]:FindFirstChild("Humanoid") ~= nil and list[i] ~= figure then
            if (listTorso.Position - figure.Torso.Position).magnitude < distance then
                distance = (listTorso.Position - figure.Torso.Position).magnitude
                targetTorso = listTorso
            end
        end
    end
    list = nil
    return targetTorso
end

function fire(v)
    Tool.Handle.Fire:play()
    local torso = figure:FindFirstChild("Torso")
    local missile = Instance.new("Part")
    local spawnPos = figure.Head.Position
    local sp = figure.Torso.CFrame.lookVector

    spawnPos = spawnPos + (v * 3)

            else bMissile.CFrame = bMissile.CFrame + (torso.CFrame.lookVector * 1.25) + Vector3.new(0, .75, 0) end
            bMissile.Parent = game.Workspace
        end
    end
end

function grenade(v)
    local head, torso, player = find("Head", figure), find("Torso", figure)
    if head == nil or torso == nil then return end

i want to make it so it shoots enemy team only not any player. so it does not shoot its own team mate it only shoots at enemy.
