Envelopment

The envelopment is basically swinging around the opposing team, in such a way that you end up behind them. However, this does not mean your running away from the attack. It mostly means that you move one of your flanks to the basis, and let them be driven backwards, while your basis and your other flank make a circling motion around one of the enemy flanks. This is a motion, which can be useful in maps where you can reach the opposite side in three ways: through the west, through the middle, and through the east. It allows you to put pressure on the back of an enemy offensive and cut them off from reinforcements and supplies. This movement can mostly be done when the enemy leaves an opening along the sides of his offensive, or doesn't attack at all there

Double Envelopment, or Pincer movement

A pincer movement is basically a movement, which works in the same way as the above-mentioned movement. However, the goal is now reached by not moving the flanks and the basis, but by the following motion: Attack with your flanks and move forwards, but let your basis slide back. This will have the effect that the enemy, seeking the soft spot will concentrate more on attacking the basis, whilst leaving the flanks as they are. After a minute or so you will see that your flanks are in a more forward position then the basis. Now you fold the flanks inward the effect that you can attack the enemy force in the back.

Turning

This movement is similar to the envelopment in that you try to turn away the frontline from you fortress/base, by moving your entire team around the enemy's team. Its use within TeamFortress is very limited, as you would open up your base to the enemy. However, it can be viewed as a means of taking over the initiative of the enemy, as suddenly you make pose a threat to his fortress/base. This forces the enemy to reevaluate his position: press on with the offensive or return to a defensive movement? As stated, in its academic form this is a limited-use movement. But it illustrates well how you could take the initiative from the enemy.

Penetration

The penetration movement is the most widely used movement within TeamFortress. Basically you try to force an opening at strategic points within the game. By attacking these points you will be able to move through the frontline into the enemy's backyard.

Hot pursuit

As soon as the enemy falls back you can do two things. Stay put, or start the pursuit. The pursuit is an offensive movement, which has, as its objective to attack a retreating troop and keep up such a pressure that the enemy will not be able to organize an effective defensive position. Unfortunately, in TeamFortress most people will attack and fight till the death. However, it must be clear that as soon as the enemy's offensive starts to get thin the counter-attack should be opened, regardless of what the enemy has standing in the field: a thinning front usually means that he is setting up his defensive.

Oblique

By moving forward the enemy thinks you are attacking on a normal head-to-head basis, but you move your troops in such a way that one of your flanks touches the opposite flank first. The enemies flank will give way and you create a gap between the base and the flank through which you can attack the, vulnerable, rear. In TeamFortress this is movement is of lesser importance, as it will almost never happen that you and your enemy are in full view of eachother.

Feigned retreat

The last of the basic offensive movements is the feigned retreat. This means those as soon as the offensive of the enemy starts you retreat. You don't allow any engagements, which will confuse the enemy (why are they running?) and will make them bold (We made them run by just showing up!). This boldness can then be used to crush the enemy by starting a counter offensive (Remember, you are in the advantage as your troops are in a smaller area then the enemy) and hitting the enemy through one of the other movements.
