Advice gleaned from Iraqi message boards:

A Mujahid for Allah – Baghdad of Al-Rashid:
In the name of Allah, the most gracious, the most merciful.
They want it a war, so be it. We are up to it, God willing.
My brothers, heed these recommendations:
1- Prepare weapons and ammunition.
2- To avoid their mortar fire, do not gather in large numbers at one place in your areas.
3- Spread out in small groups, and assign a commander to each.
4- Always take cover behind a barrier (anything that can protect you from enemy fire).
5- If there is an attack against your area, try not to waste your fire (make maximum benefit from the ammunition you have available).
6- Assign duties to your brothers.
7- Maintain communication with other groups in your area so you can respond to any breach of the area by the attackers.
8- Have courage and patience when you face them. They are cowards and will be defeated.
Remember that your brothers, the Mujahideen, will be with you in your fight against the murderous criminals. May God save us and save Iraq.

Abu Mohammed – Baghdad:
I recommend to my brothers the following:
1- Trust in God, and defend your family, your possessions and your honour. Whoever is killed is a martyr for God.
2- Never surrender, because in that case they will kill us after maiming and torturing us. We should fight to the last breath.
3- Ensure surveillance for every area, especially main streets and entry points, and maintain communication to follow the movement of vehicles used by militias. Attack them wisely without wasting ammunition.
4 – Prepare ambushes for these militias on the streets they are expected to pass. Finish them off and take their weapons.
Remember that those militias are former looters, thieves and shoe shiners. Do not make such a big deal of them because, by God, they are lowly animals.

Abdul Rahman – Iraq:
Please keep these steps in mind:
1- Deploy snipers on the rooftops of buildings that lie close to the main entry points for each area.
2- Prepare positions for medium weapons at a distance from the entry point, and make pincers with sniper and PKC fire. When you choose a position, make sure you can retreat to alternate positions from it, in case the enemy overruns the area (do not choose a building that is not adjacent to another, or use ropes to quickly slide down the building).
3- RPG carriers should maintain their positions on side streets and take cover behind barriers. Do not fire just for the sake of it (attack the first and last vehicle).
4- Create heavy fire density to force the enemy to take cover, and then eliminate them by sniper fire.
5- Provide hand grenades and distribute them to the Mujahideen.
6- Fighters with light weapons should always change positions, fire from different angles and not stay at one place.
7- Prepare and plant roadside bombs on the entrance to every area.
8- Bomb the gathering locations for the army of filthy Muqtada.
9- Prepare a special group to deal with any breach, and it should be armed with RPGs, PKC machine guns and KIA vehicles.
10- Plan ambushes and lure the enemy by using bait vehicles that they chase to be dragged into the killing zone.

Abdul Rahman – Iraq:
For the brothers who have not used weapons before, please take this advice:
1- Check your weapon if you have not used it before. You can ask your neighbour to teach you how to attach the magazine and to load and fire. Do not be ashamed that it would be said you don’t know how to use a weapon, as many people have not had a chance to.
2- Choose the appropriate spot on your roof that can provide you with cover and make it hard for the enemy to target you.
3- It is best if every two families gather in one house when the alarm of an attack is raised to keep spirits high.
4- When you shoot, try to make it intermittent so you do not waste your ammunition. Be patient until more fighters arrive and your neighbours start shooting too.
5- You may feel fear upon using a weapon for the first time or that something bad would happen to you, but think of your family and what awaits them if you are hesitant. Keep your honour and your children in front of your eye, and remember that they have burnt children with kerosene.
6- Make sure that you have an extra magazine because in the midst of action you may take away your weapon and forget your extra magazine. It is preferred that you tape two magazines together. Ask your neighbours how to do that. Practice with it several times.
7- Fear of using weapons will disappear with the first shot. Do not hesitate to pull the trigger and concentrate on hitting the enemy.
