How would I go about making my follow script detect the model closest to them?

The title explains my problem.

if string.find(script.Parent.Name, "Blue") then
    EnemyTeam = "Red"
else
    EnemyTeam = "Blue"
end

function findTarget()
    for _, v in pairs(game.Workspace:GetChildren()) do
        if v:IsA("Model") and string.find(v.Name, EnemyTeam) and v:FindFirstChild("Humanoid") and v ~= script.Parent and v.Humanoid.Health > 0 and not game.Players:GetPlayerFromCharacter(v.Parent) then
            script.Parent.Humanoid:MoveTo(v.Torso.Position)
        end
    end
end

while true do
    wait(.2)
    findTarget()
end
