Chainmail, the cool thing about Thermobaric is they don’t do a lot of collateral damage and they don’t set the whole block of building on fire. The heat is instantaneous and they can be fired at 350 meters from the target.
The M2A2 only had a range of about 20-40 meters and the flame only lasted for less than 30 seconds. Getting within range to use the weapon killed it, coupled with the bursting hazards of the fuel on your back.

That isn't to say that the thermobarics aren't excellent weapons and absolutely necessary - but it's apples and oranges as far as tactical applications go. I volunteered to take some over to Fallujah and train Marines to operate and sustain them but they weren't interested in old washed-up flame operators... Ah well.
Very proud of your efforts to improve our Marine's weaponry and capabilities - hope you're still at it - we need people like you (and big budgets)
