Ok, tactics...Guys get on this forum and ask for good tactics. All I ever see is "flanking" "supressive fire" Junk like that.
I don't think I've seen any one mention the 3-5 second rush.
This is a movement technique used for moving short distances quickly, while under fire. You need at least 3 people to make this work effectively.
So, you need to take a fortified position, or just move toward an enemy position for any reason, they know you are there, and will be shooting at you. The technique is very simple in theory, but takes some practice to train yourself.
All players will start in the prone to avoid being shot. Call out "moving" player one pops up, and runs as fast as they can for 3-5 seconds, using as much cover and concealment as possible. REGARDLESS of where you are after 3-5 seconds, DROP. Call out "Down". That is your cycle.
Each player will repeat this until you objective is taken, or you have sufficient cover to mount an aggressive front established.
I would not reccomend having more then 3 people up at once, depending on how many players are on your team, if you have a squad of 9, I think three would be good. If the enemy has 9, I would not rush more then 2 players at once, because there is more chance that one of the 9 will get lucky, or already have his weapon oriented in the direction of a player. In MY mind, a 1:3 ratio is good, if playing with 6 on your squad, 2 at a time, OR if 6 enemies 2 runners at a time.
When you are "down" if you can, return fire, do it. DON'T fire while you're running, just run.
The theory behind these techniques is that the enemy won't have time to switch targets, acquire you, and fire, in the time that you're up. If your team fires while you are up, it will put more pressure on the enemy, which will slow their reaction time even more.
Another related technique "I'm up, he sees me, I'm down."
This is used to gather visual confirmations under fire. While you are taking fire from enemy positions, you need to peek out to see where your opponents are, how many, and if they are moving. Rather than slowly peek your head around a corner, or up over a rock. Try this.
Pop up, full torso, and look around. Actually say this to yourself "I'm up, he sees me, I'm down. While you say "I'm down" you should be moving down. In airsoft, you can take your time in saying this, because you have to take into account, BB flight time. In a real fire fight, 2-3 seconds is enough. In airsoft, I think 3-5 seconds is safe. The principal is the same as the 3-5 second rush. It takes time for the enemy to see you, aquire you in his sights, fire, and the BBs to hit you.
if you do it every 30 seconds though, they might pick up on a pattern and time it right, OR leave their weapon oriented on where you will pop up. So your team needs to be doing the same thing, like the whack a mole game. All the while you are relaying intel to your team, so your team leaders and other elements are able to assess the situation and make a good plan of action.
I hope this helps you all out.
