Some mounted situations may call for you to combine and use both methods. Just remember the characteristics of each.
- Terrain association is fast, is error-tolerant, and is best under most circumstances. It can be used day or night if you are proficient in it.
- Dead reckoning is very accurate if you do everything correctly. You must be very precise. It is also slow, but it works on very flat terrain.
- You frequently will combine both. You may use dead reckoning to travel across a large, flat area to a ridge, then use terrain association for the rest of the move.
- You must be able to use both methods. You should remember that your probable errors, in order of frequency, will be-
- Failure to determine distance(s) to be traveled.
- Failure to travel the proper distance.
- Failure to properly plot or locate the objective.
- Failure to select easily recognized checkpoints or landmarks.
- Failure to consider the ease of movement factor.
