I think he's bracing himself, not because he's concerned about the recoil, but more because he's worried about being hit by a ricocheting bullet, or flying ice fragments.

Question: which other planet is, on average, closest to planet Earth?

Right now, Venus is closest, at 115m km. The sun is at its usual ~ 150m km. Mars is 211m km away and Mercury 212m km away, nearly twice as far away as Venus.

Distance, Brightness, and Apparent Size of Planets - you can select different dates.

This Sunday (for some meaning of that) there will be a lunar eclipse. It's viewable from the USA Sunday evening, and from much of Europe in the predawn hours of Monday morning. Before and after the eclipse, the moon will be unusually bright, because of the current distances of the sun and the moon from Earth. It's the brightest since 2010 and there won't be brighter one till 2030. However, the brightness doesn't really vary that much, so you won't be able to tell without sensitive measuring equipment.

He was carrying in the non american style, needing to chamber a bullet to fire the weapon. As this is the safest way to carry the weapon, it's discouraged in america, since you can see it slowed down his reaction time and that's when the immigrants get ya!

(Of note, this is old enough that the Mythbusters tested it and found that it is quite real.)
