The Irish army's latest battle might be against flowers.
But these aren't just any flowers. At least one Irish politician has called them "aggressive" rhododendrons.
They have taken over about a third of a national park.
"The rhododendron situation in Killarney National Park has gone so bad that nothing short of calling in the army is going to put it right," deputy Michael Healy-Rae said.
The minister overseeing the park says his department has it under control and has spent a lot of money to control the flowers.
So Irish army, you might want to hold off on declaring war for now.
