This is a very old film technique which is applicable to MS. The purpose is to create Giants and/or dwarfs through the use of "Forced Perspective" I would have used a green screen to have the puppet stand in front of the guards but didn't to show that you do not need any post production to do it.
If you want the guards to be 30% bigger than the puppet, the they need to be 30% closer to the camera and vice versa. Both guards have to sit on a mesh so that the feet appear to touch the same floor the main puppet is walking on.
The most difficult part is to make the puppets look at each other correctly, for that you have to setup props as "targets" and make the puppets look at them.
This technique was used on Lord of the Rings on some of the scenes.
