how to make Realistic Destructible Walls?

I was wondering if there was anyway of making more realistic destructible walls for example the ones in Rainbow Six Siege?

make a wall made of smaller parts put together to make a wall, group them make them anchored add an ontouch script into all of the parts

script.Parent.Touched:Connect(function()
script.Parent.Parent.(partname).Anchored = false --clone this line for all the parts in the model
