I think you are missing the point of 'combined arms'. Phalanxes themselves are easy to use: just march towards the enemy, lower your spears and start poking. But to use them effectivily you need to support them with other unit types. And that is part of a complete battlefield guide, not one dedicated to one unit type. Horse archers got a guide of their own because they work relativily independently from the rest of the army (though they still require support to be effective) and they need a bit more care than most other units. Also, not everyone was able to find out how they should be used. None of these three arguments apply on 'ordinary units' and anyone who had read a good battlefield guide should be able to work out how they should be used.
