Why Is the Trump Administration Selling Giant Sniper Rifles to Ukraine?

This one seems pretty obvious, so the Ukrainians can fight back against pro-Russian Separatists? This link explains our position on Ukraine per the State Dept. dated Sept 2016 - https://www.state.gov/r/pa/ei/bgn/3211.htm

so they can reach out and touch someone of course... it would seem that the 50 Cal is the new standard for sniper weapons.

Military conflicts and unstable regions are big business for the defense industry. The Trump Administration and GOP supports the Defense Industry not the military.
