The last rank of a unit is very often incomplete and if the units decide to turn 90° or 180°. It can cause a problem on the final formation. The best thing to do is to turn the models in the complete ranks first and then remove the incomplete rank and move its models to the back of the new formation, forming new ranks if necessary (Fig. 3). In extreme situations (long lines of missile troops mostly) this can look a bit bizarre, but on the whole this is a simple principle and helps in keeping the game tidy.
