Re-reading past stories

While rereading past stories

I was reminded of a story it is a scifi, accidental change, forces.
I'm almost 100 percent sure that it isn't alien artefact related so rules out:-
Breanna Ramsey's 'Genomorph' & Morpheus' 'Legacy Universe' 'Hardshell', I reread The Legacy Universe after began posting 'The Return of Nevermore'

It is a man made science project, may be futuristic, not Desiree Jones' 'The Bronze Maiden'.

However there was police involved, maybe swat, science experiment to make Tactical APS (Hardshell), can't remember if the officer/soldier was injured and a result was offered the position in the project.

Or is this my memory playing tricks and merging elements of multiple stories.
