Whelp, I'm definitely not playing Battlefield 4. Well, I mean, not unless the NPC gets his nuts bitten off later on in the game and dies screaming at the top of his lungs like a 12 year old girl. But, yeah. This is modern shooters in a nutshell. Pretending to be gritty and edgy by killing things that appeal to our emotion (Children, dogs, innocent people) and then not really actually having anything 'edgy' or 'gritty' to say about war. (Let me guess, the plot involves you saving the world from another world war, right? Yeah, thought so.) So while they may pretend to have depth by shocking us by showing us some things we may dislike about war (Nuclear bombs, children, dogs) they pretty much undermine anything they have to show us by then turning around and then giving us an easy answer. (Like say, all those people, children, and animals you murdered in cold blood being for the greater good because hey, you saved the world!)
So, to an extent, it almost defends these acts.
So I guess I'll share a real gritty fact: Dogs that are in the military (Fighting in a war for a far more brutal, savage, and selfish species that they shouldn't be fighting for) are usually hard to find homes for once their 'service' ends.
Humans fight wars, and only humans should die in them. Preferably only those that choose to volunteer.
