Lets say it costs 10,000 a month per solider, which includes things like Monthly pay, over seas pay, food, water, ammunition, kit etc. It would cost 20 000 000 a month just for personal. Then you have to throw in the cost of flying a Airbus at a wild guess of 200,000 for crew, fuel and repair or the Antanov at 1 million per shot, every week to Mirage for mission resupply, 1.6 million per month (if you sent 3 airbuses and a antonov per month) . Then lord only know how much we pay every month of truck fuel and other expenses related to camp operations.
So my rougher than not shaving for 3 days guess is 25 million a month.
With a grand total of 150 million for the tour.
