Hints and Tips – Arma 2

Introduction

ArmA II is not like other FPS. It is a simulation. Most, if not all that you learned in other FPS is wrong. You cannot stand out in the middle of an open street or field and expect to survive long in a real battle or in a simulation of real battle. Bouncing around in full kit in real battle does not stop you getting shot; and it tires you out real quick, and would probably break your ankles; so just as you would not do it in real life you cannot do it in ArmA II. You have no ubber body armor, no magic medipacs, no bunny hop rocket boots. It is just you, and what ever weapons you are carrying. If you get shot any where important you are going to die, often right away.

If you are a New Guy you are going to die and you are going to die a lot. Sorry but that is just the way it is but there are ways you get over the boot camp hump faster. That is what this section of the wiki will help you with.

The ArmA II Bible

Battle Drills

This page links to the basic Battle Drills

Battle Drills are the basic moves to perform in battle, they are a subset of Standard Operating Procedures (SOP) that are trained in the military to replace the normal human reaction to threat of Fight, Flight or Freeze. This reaction is hard coded into to your Amygdala. The Amygdala reacts much faster than the conscious brain and can short circuit it. The idea of training a Battle Drill or SOP is to replace these reactions with useful actions.

Firing blindly may kill your buddies who are likely to be closer and thus occupying a larger percentage of your Arc, thus the Fight Response is replaced with the React To Contact Procedure.

Altering the Flight Response so that you do not get shot in the back is also useful, the highest casualties in war happen during head long retreat, it is very hard to fire over your shoulder while running in the opposite direction, so the Battle Drill that replaces head long retreat is the Break Contact Drill.

Also the Freeze Response is not always beneficial, freezing in the same spot that the enemy is putting down effective fire on, does not stop the bullets, the Freeze Response is replaced with the Basic Drill.

The difference between cover and concealment

Concealment is something that prevents you being seen.

Cover is something that prevents you being shot.

Concealment once busted is no longer concealment. Shooting or moving around, making a noise, or sky-lining your self, all bust concealment. Examples
A bush is concealment not cover. Bushes do not stop bullets. That said unlike other games ArmA II AI does not see through bushes. but running behind a bush, does not magically make you concealed from an enemy that saw you run behind it. Most of us learn this with the peekaboo blankie game as babies.

A tree less than two foot thick is neither concealment nor cover. An AT rocket or pair of shoulders, beer gut, your fat backside, or rucksack; sprouting jauntily out of the side of a tree, attracts curious stares from both human players and AI, usually followed by bullets; which incidentally any thing less than a two foot wide tree will not stop. Interestingly even with a two foot thick tree, only one foot of a tree in cross section is near two foot thick in the line fire, as you move to the edges the thickness of wood decreases exponetialy.

True cover is: Multiple walls of say more than one house, bullets of 7.62 calibre and above will go straight through most houses.

Thick lumps of terrain such as mountains are excellent cover.

There is a further detailed discussion here of the difference between cover and concealment on the BIS forums.
