Mouse Trap Ambush
This was repeatedly used in Vermin War IV.  I love doing this.  It is simple, and oh so effective.  This is very similar to the above ambush plan, but is used to trap individuals, or squads instead of armies.  So that you can isolate and destroy.  First you need a scout, we used someone with a SC 400.  The scout runs at the enemy squad or duet, and shouts something like "BITE ME SUCKERS!" then they rush at the enemy, soaking them and getting soaked them self.  Then the scout backs up firing in wait for the enemy to attack.  If the enemy attacks then run back to where your team is ambushing (we used a person on each side of the path with CPS 1200s and XXP 175s).  If not then keep taunting or fighting until they do give chase.  Once the chase is activated have the scout run towards your position.  Then its very simple.  One only has to yell "ATTACK!" and soak the enemy.  Your enemy will be surprised, and drenched.
     L ambush
In the L ambush one group of your team (the smaller of the two) makes a line accross a path or somewhere visable to the enemy as a defencive formation.  The larger force finds cover, somewhere else nearby at a right angle to the first squad, creating an L like shape.  This was used once in Vermin War IV... while I've said this alot for the above plans I do not list all... for all do not work.  Anywhoo this does.  The enemy should attack the smaller part of the L as it looks vulnerable (the guys in the larger portion should be hiding).  This can be done with three or more people as long as you have less people on one side.  We used three for a squad entrapment, then had a Pincer movement done by the other to complete their encirclement.  Now, as the enemy attacks your smaller open force have your main force swing down like a door firing their blasters, and hitting the flank of the enemy just as the enemy is in the heat of combat with your smaller force.  The smaller should have an artillery peice, and a hold out gun (ie XP 110, XP 150, XP 250), along with maybe a few others depending on the units size.  Your larger force should mainly be large quick firing rifle.  Nothing larger than a Monster X, or smaller than a XP 105 since you will need both mobility and power.  I reccomend a CPS 1500/1700, XP 105, XP 310, and CPS 1200 to be the or apart of the larger flanking group.  The flanking group "L" will sweep down the enemy almost into a circle.  This then surrounds and anhialates the enemy, just have grunts with XP 310s, or XP 110s do circle of deaths on the entrapped enemy.
     One Person Ambush: Urban
    When an enemy is hot on your heels and your a little ahead, and slightly faster do this.  Simple, I have had this done on me lots of times, and did this alot to enemies.  You can use it in a one on one or two o two squirt fest with no rules, or in a highly involved war.  When the enemy is coming after you run around the corner of a building put your gun on the highest setting, turn around and blast!  Simple, and effective... just pray they don't have a SS MDS, even though you could kill them anywhere else it is extremely anoying when someone fires at you from around the corner and then you go there and they are at another corner.

Reacting to  Ambushes

React to Near Ambush

• Turn towards the enemy and fire upon them, tactically retreat firing if you are outnumbered massively
• Send specialty soldiers as needed (flanking, snipers, etc.) to clog backup retreat routs by the enemy, so they cannot retreat
• Suppress them with fire forcing them back to your specialty units
• Clear enemy units as needed

React to Far Ambush

• Get down and take cover
• Team in contact lays down suppressive fires
• Call out distance and direction of ambush to confirm it is a far ambush
• team not in contact moves to flank the ambush
• team flanks and assaults through (use predetermined signals)
• conduct specialty teams as needed (flanking, snipers, etc.) to clog backup retreat routs by the enemy, so they cannot retreat
