How to script movement for a simple imported character?

I have imported a simple Soldier rig from Blender. The Rig is animated and I need it to move like a normal roblox character would do. I have tried scripting like:

while true do
	Soldier.RootPart.CFrame=Soldier.RootPart.CFrame*CFrame.new(0,0,-0.1)
	wait(0.1)
end

This makes the Character move but it doesn't work when going uphill/downhill. I just need to know how to make the Soldier Character move around like Normal Roblox Characters. Any help is Highly Appreciated. Thanks in Advance.

You can use Humanoid:MoveTo() just as what @JustinWe12 said, but Humanoid:Move() is much preferred if you want a humanoid to walk in a direction.

-- Normal Script inside the Soldier Character
local Solder = script.Parent
local Humanoid = Solider:FindFirstChildOfClass("Humanoid")

for _, limb in ipairs(Soldier:GetDescendants()) do
	if limb:IsA("BasePart") then -- if it's a limb (Part, MeshPart, Union, Accessory, etc.)
		limb:SetNetworkOwner(nil) -- so the solider won't lag
	end
end

Soldier.DescendantAdded:Connect(function(limb) -- if a new limb is added to soldier
	if limb:IsA("BasePart") then -- if it's a limb (Part, MeshPart, Union, Accessory, etc.)
		limb:SetNetworkOwner(nil) -- so the solider won't lag
	end
end)

while true do
	Humanoid:Move(Solider:GetPivot().LookVector) -- makes soldier walk forward
	task.wait()
end
