NOT SO FAST!!
The Army is retaining 51 UH-1H's in various facilities in the US. Mainly because the UH-72 cannot haul the volume size of loads that a Huey can. This info came from the Program office at the AAAA convention in Nashville this year. The UH-72 is a fine aircraft but smaller and way more expensive.
I am fortunate that I fly an H model every summer season for the Oklahoma Bureau of Narcotics. We use it for Marijuana eradication including rappel and STABO of agents. Don't think there is a method to haul six agents and crew in a UH-72 and rappel.
