Largo's new police Chief John Carroll made his first major personnel change recently, promoting Brian Browne to captain.
Browne will assume command of the department's operations division next month.
Capt. Glen Smith will assume command of the department's Administration Division.
"Once again, I had the difficult choice of making one promotion from a pool of exceptional candidates, and I am extremely proud of them and this entire organization," Carroll said.
Carroll said he also expects to promote several other officers to lieutenant and sergeant in the coming weeks.
"There will be lateral movement at the rank of lieutenant, and there will be numerous opportunities for internal transfers as vacancies occur," Carroll said in a statement.
The recent departure of longtime Largo police Chief Lester Aradi has set off a number of changes, starting with Carroll's promotion from deputy chief to chief.
