Went ahead and looked through the comments to see if some one already asked:


 * Klein is using a Pulse Rifle, from the movie Aliens.
 * Silica's bot is a Dragonfire drone, (as depicted in Black Ops II)

Doesn't seem like anyone asked, just some people pointing out the weapons, and the artist affirming their suspicions.
