Active duty (regular army) troops train for that kind of mission all the time. Hard to judge Intent by anything except overt acts -- I had numerous training sessions carrying an M-14* against imaginary civilian crowds, hypothetically just outside the base gates in beautiful Eatontown, New Jersey.

And we weren't even a "combat arm", being a Signal Corps school installation.

*The M-14 fired a 7.62 mm NATO cartridge, which would penetrate multiple bodies at crowd-control (point blank) range.
