First engagment:Summary:
Move,
communicate,
set up individual targets,
fire at the same time,
rush if contact fails,
fan out if rush fails,
sporadic rush/advance with infantry fighting line.
Speed is the main key in Airsoft. Move as fast as possible, and do not over-encumber yourself!
Remaining undetected is a key in any battlefield sport. Do not talk, do not tramp through bushes, no not use high-caps or have loose ammo in canisters. Use
familiar hand signals only.
One thing you have to do is learn to move with your team, which Osprey details up above.
After you have squad movement down, you should move on to how to react to contact:
When you see an enemy, don't immediately open fire on him. Instead communicate his position with you team, and be sure to check for other enemies, especially NOT near the enemy you have spotted. After that, If there is time and opportunity, move to a position where you will most definitely have the advantage if the skirmish goes sour.
Now, you are all set up. Everyone in your squadron knows the location of every enemy, and you are in a position that allows you to rush immidiatly after contact. This process should take about 20 seconds or less. Each team member should have their own target enemy, and all enemies must be targeted.
All of your team mates should open fire at the same time, firing for as short amount of time as possible. If all enemies are eliminated, move on. If not, or if more enemies arrive, it is time to take the offensive.
Quickly (2-3 seconds after cease fire) arrange your squad and upside-down "V", where the "point" man is closest to the enemy. Space out as much as possible up to about 20 feet, so you retain firing advantage. Then you must commence the rush. It is now OK to tell out in communication with one another. At this point, hand signals will now only slow you down.
Rushing takes practice. The guys in the back of the "V" must provide as mush cover fire as possible to keep the enemies in cover. They should try to predict when a baddie will pop his head out. The point man and possibly the two immediately behind him must then rush up and try to eliminate the enemy cover advantage before they have a chance to dig in. try to do this rush in that split second that they look down to check their footing or when one stumbles, as to have the element of surprise.
Pay attention to the enemies to know when to stop: Cease the charge once the enemy is in a position where they can fire on you from cover.
You must now fan out into a "Infantry Fighting Line," or IFL for purposes of this instruction.
Each member of the team should be spaced out evenly (10-20 feet apart) in as straight a line as possible parallel to the enemy cover. From the IFL, you should be able to eliminate any enemy who tries to move from cover to cover.
Each member of the IFL will move from cover to cover AT THE SAME TIME, SHOOTING while you move, and while you are in cover.
The idea of the IFL is to shrink the enemy cover so that they cannot hide. This is achieved by constant motion toward the enemies at a diagonal, like so:

The whole squad moves up until the point man, who should be on the end of the IFL, is able to rush forward and eliminate covered targets from the side by flanking them. At that point, the squad pivots around the suppressive fire man (IE saw gunner, etc... opposite the point man) and overtakes the enemy position by quick rushes or forcing them out of cover. This maneuver is risky and takes much practice to make effective.
There are two things that must NOT happen after contact is made: do not stop and take cover for more than a few seconds, and do not rush forward blindly. Always work with a team that you are familiar with.
That is one of the most effective ways to resolve skirmishes as victors. There are different ways to attack for snipers and marksmen, as well as Gunners. There are whole different sets of tactics for things such as Responding To An Ambush, Assaulting a Multi-sided Fortified Position, Moving with Sniper Squads, etc... I can PM you these strategies, or just about any that you need to know.
These tactics do not work in all types of terrain, or with all types of people. You must be fast and not afraid do die and try again until you get it right. Feel free to edit them in any way that fits your style of play, team, or skill level... or size.
The bottom line is that working with strategy takes a whole lot of practice and time on the field. Attend as many games as you can, and find a local field to go to on weekends.
This will bring you from "entry level" to "pro" if you can master it.
This strategy came from Drill Sergeant James Cummings, retired E6, Army, my father.
