If you were a member of the Guard or Reserve in 2017 and travelled more than 100 miles for drills, you may qualify for a special tax break.
"If you are an Armed Forces reservist or Guard member and travel more than 100 miles away from your home to perform reserves service (such as drills or meetings), travel-related expenses can be subtracted directly from the income reported on your tax return as an adjustment to income. You do not have to itemize deductions to take advantage of these benefits. Also, unlike most other employee business expenses, the deduction for these expenses is not subject to the standard 2% Adjusted Gross Income (AGI) limit. Allowable expenses include those that cover overnight transportation, meals, and lodging." from Tax Considerations for Reservists
