I'm getting a lot of messages from this one. The first is the fairly straightforward concept that the pen is mightier than the sword. Here you have a dude in every piece of tactical gear you can wear, but when surrounded by the proverbial pen (colored pencils in this instance), he is shaken to his core. Also note there are more of them than there are of him. Ultimately our voices are loud and many. That's what terrifies any power who is trying to maintain control through violence.
The other reading of this image is a bit more intense. It reminds me of the Ferguson protests. I see the colored pencil representing people of color. We've seen that military opposition has been sent to clash with many of the protests led by people of color. Replace those pencils with real people and this image isn't so different than something we've already seen before, is it?
