Deep inside the verdant and sweltering vegetation of Nicaragua's Mosquito Coast, a specially trained army unit is waging a new kind of war against a new type of enemy.
Operation Green Gold is the inaugural mission of Nicaragua's newly formed Ecological Battalion.
It is Central America's first concerted effort to seek a military-backed solution to the threats of climate change.
The green guard, a unit of 580 environmental soldiers, recently won its first "battlefield victory" by netting 111,800 cubic feet (3,165 cubic metres) of illegal lumber felled by loggers.
The trees were chopped down in Cerro Wawashang, a nature reserve that is being plundered to supply the black market for construction materials.
The eco-battalion, working in conjunction with state prosecutors and forestry officials, discovered the lumber contraband hidden under netting and brush to avoid detection from the air.
The troops are now reportedly on the trail of the criminal organisation that was extracting the wood from the jungle on riverboats.
"There are unscrupulous people who are taking advantage of the economic limitations of the people in this region.
"And in the end, it's the outsiders who benefit while the local communities are left with the indiscriminate deforestation," says Col Nestor Lopez, the army's chief of civil operations.
In a country with 71 nature reserves and other large areas of thick, primary forest, Nicaragua's precious hardwoods are tempting booty for timber traffickers.
Since 1983, Nicaragua's forest cover has dropped from 63% to some 40%, according to government data.
Not all Nicaragua's deforestation is caused by the lumber mafia - farmers and cattle ranchers are also doing their fair share of careless chopping.
But whoever is responsible, at the current rate of clearance only 25% of the country is likely to remain forested by 2030.
Reserves such as Cerro Wawashang will be reduced to scrub brush and grass, according to the military's projections.
