The Michigan State Police have identified 48 posts across the state that will be affected by 100 trooper layoffs announced earlier this week.
Eighty-two of the troopers to be laid off June 28 were trained through a trooper school that graduated in December.
Eighteen relatively low seniority troopers from a previous training class also will be laid off.
The layoffs are expected to save $1.7 million, but the state had spent more than that training the troopers in recent years.
State police said Friday five troopers each will be laid off at posts in Ypsilanti and Flint.
Sixteen posts will not have layoffs.
The layoffs were sparked by an executive order issued by Gov. Jennifer Granholm and approved by state lawmakers Tuesday.
