Should Soldiers be given an allowance per month for gas?
Seriously the Army cannot nor will not provide for in and around mileage in the local area. Also, I don't think they should be expected to. Also, "When it is determined to be to the Government's advantage" what is the advantage and huge expense of filtering all these requests. There is a certain implied task with all jobs.
I do think there are some things leaders can do to mitigate the travel of their Soldiers. However , we get expenses far beyond our civilian counterparts - I have seen 34 years of my fathers career and know as part of a major corporation we treat our Soldiers and families far better.
Also, realize ever Branch treats it Soldiers, Airmen etc... different. My Soldiers lived in the same barracks while another branches Soldiers received substandard housing allowance - but that is another story.
Again as stated while it would be nice than what other expenses and where do we stop?
