The video shows an Italian Forest Service Hughes NH 500 filling a Bambi Bucket from a variety of water sources, and then finally at the end shows it dropping water on a wildfire.
Here is a description of their firefighting helicopter program:
“Among the Italian Armed Corps, the Corpo Forestale dello Stato (CFS, Italian for Forestry Service) acts as a police and ranger force, responsible for protecting Italy’s natural and environmental resources and eco-systems. Its duties include the prevention of environmental violations and wildfires, safeguarding animal species, ensuring antipoaching and habitat protection, and providing SAR in mountainous areas.
The CFS has a fleet of helicopters which includes NH-500Ds, AB-412s, Erickson S-64Fs and AW-109Ns used for fire-fighting, early spotting of wildfires, and coordination of other aircraft or with ground-based firefighters.
The Service also owns a P.180 fitted with a forward looking infra-red (FLIR)/TV camera system for ground surveillance in anti-pollution monitoring and geological/wildlife control, which can easily be configured as an air ambulance by means of a medical kit, and can ferry specialized teams or VIPs to various helicopter stations.
In summer, the aircraft are strategically deployed in areas where wildfire risk is higher.”
