Indian Run
Requires the newest version of Macromedia's Shockwave to Play Movie
The Indian Run formation is somewhat of a leapfrog tactic, best used to cover a medium to long distance. It is mostly a varation on the standard line.

The team stands in the standard single file line. The man at the #1 position will face foward. #2 and #3 will watch the rear, with #2 keeping an eye on the left if necessary. #4 will run from the back of the line up to the front, facing foward and watching the right if needed. He will then take #1's place, #1 will take over for #2, etc. The team continues this way until they reach their destination or switch formations.

Advantages

Allows a constantly-moving line, with two marines facing foward and two facing back. Since the other members are stationary, they can concentrate on guarding their areas instead of dividing that among watching and moving. The added movement may also confuse aliens, especially if you mix up which side the running marine runs on.

Disadvantages

As with the standard line, the sides are still vulnerable, especially in narrow corridors. Also, if an alien should surprise the group, either by dropping from a vent or lashing out from a door, there is an excellent chance at least one marine will be killed.

Best used in

Areas where you need to get from point A to point B with as much protection as possible. The Indian Run sacrifices the flat speed of the standard line run for a more controlled, cautious advance. In some areas, such as the Coro "hall of death", FTLs may find it better to run through top speed than to try and carefully advance through it.

Where the Indian Run really shines though is in a retreat. Simply have the running marine move away from the enemy, instead of advancing on them. This will give a rapid retreat, but still allow good cover fire for the team.
