Need method to subtract one object from another

[Steve5F87]

I have a vector graphic in ai format.  There are three objects (people) with the left object in front, middle object behind the front and right object in the back.  I want the left object to cut the vectors behind it from the middle object and then  the middle object to cut the vectors behind it of the right object. I have tried pathfinder without the result I want.  The end use is with a laser or mill to follow the vectors.  Do I need to try paths?

This shows my issue better. I need the paths to not overlap between objects (people).

Can you share this Illustrator file (.ai)?

Which version of Illustrator are you using?

The file is someone elses IP, I only bought a use license.  Just downloaded AI today from the site and installed.

Version 25.1, update says I am current.

I can move the objects around.
