Two Swiss organizations have examined 19 games (including "Metal Gear Soldier 4") for their compliance with/flouting of International Humanitarian Law (IHL), and while their intent is serious, the way they hold these games to IRL IHL gets a little wacky.
The study, "Playing By the Rules" was undertaken by Pro Juventute, a Swiss children's rights group, and Track Impunity Always (TRIAL), which is concerned with international criminal justice. Their report provides a legal analysis of the conduct enabled by the games.
Rather than play the games themselves, the two groups sent expert observers to watch serious gamers play through and then note the egregious acts they saw. Here's what they had to say about Battlefield: Bad Company.
In the scenes, there seems to be no assessment of proportionality in the attacks realized in civilian areas and we do not know, whether precautionary measures were taken to minimize civilian casualties and damage to civilian objects. However, in a real life situation, one is often confronted with similar circumstances: regular armed forces and irregular armed groups are very unlikely to give any information about the planning of the preparation of military operations to international organisations or human rights bodies. Without such information, it is difficult to establish that a military operation was not proportional, in particular whether the attacker took all the precautionary measures necessary to avoid, and in any event to minimize incidental loss or civilian life, injury to civilians and damage to civilian objects."
In addition to the extensive destruction, some of the scenes portray the members of "Bad Company" taking gold and "treasures" found in the civilian houses they have just destroyed. Upon obtaining them, the players get points. These actions amount to pillage, which is strictly prohibited under IHL and thus have also been labeled as "strong". This illegal action is confirmed in one of the scenes where you can hear a member saying that "Pillaging is an old war tradition." Pillage is considered as a war crime both in international and non- international armed conflicts.
I'm thinking that asking the goons of Bad Company to take precautionary measures for anything would be a little like talking to a cardboard box. It's also amusing to me that a basic, nonviolent scavenging mechanic rates a "strong" violation of international law (which it would be, if it occurred in real life) and is called out as a war crime.
Anyway, the study had a number of recommendations. Among them is a call for clearly defined rules of engagement.
It would be very useful if developers would incorporate more specific rules on how to conduct an operation in their games, in terms of the weapons allowed, the behaviour allowed, the military targets sought, the degree of collateral damage permitted, etc. The message of the scenes should never be that everything is allowed, or that it is up to the player to decide what is right and what is wrong. In real life, this is not the way it works.
