Using the Environment
Using parts of the environment has always been a great defensive and offensive strategy in the SOCOM series, and it's no different in SOCOM: Confrontation. Offensively, nearly everything in the environment is destructible, including vehicles, propane tanks and even garbage cans. Blowing up a vehicle or propane tank near an enemy is a great way to attack without having to put yourself at risk in a middle of a firefight. But just as you strategize using the environments against your enemies, you'll have to be careful defensively not to put yourself in the same situation.
Hidden Switches
In many maps and game modes you'll have to blow up a barricade, bridge or wall to advance to the next area or to get to the objective. Ever wonder how to do this? It's actually pretty easy, but sometimes hard to actually find out. Once you walk up to a barricade or wall that you need to blow up, a detonator icon will come up allowing you to place a C4 or Claymore there to blow it out of your way. You'll blast your way through with no problem.
Weapons
Probably one of the most important things in playing any kind of shooter, is your weapon of choice. The two biggest key points on choosing which weapon to pick in Confrontation are which map your gonna be playing on and which game mode your gonna be playing. On a larger map you might want to stick with an assault rifle or, even better, a sniper rifle if your wanting camp out on your enemies. In a mode like Escort or Extraction, it might be smart to take on the role of sniper to clear the area for your teammates to retrieve and extract the hostages. But in a mode like demolition where you have to quick to get to the bomb, you might want to pick a submachine gun or shotgun so that you can try and get to the bomb before your enemies do. I've provided a full list of weapons available in SOCOM: Confrontation later in this guide.
Armor
One of the new features in SOCOM: Confrontation is the ability to customize your character and actually choosing different types of armor to wear. Armor provides increased resistance to weapon fire for your torso and legs. There are three types of armor: Light, Medium and Heavy. The more armor you wear, the more damage you'll be able to take. However, the heavier your armor is, the slower you character will run. So choose your armor wisely, especially depending you how your playing style is.
Attachments 
Attachments to weaponry provide a tactical advantage on the battlefield. There are many different attachments including scopes, grenade launchers, suppressors and laser sights. Always be weary of which attachments you have on your gun depending on what type of game mode your playing or which map your playing on. Playing on one of the larger levels? You might want to put a scope on your assault rifle instead of a grenade launcher. Attachments can make quite a difference in battle and can greatly enhance the efficiency of a weapon.
