If every position being located is within the same grid zone, only the 100,000-meter square and numerical location are specified. The MGRS format is designed to support measurement precisions of 1m, 10m, 100, 1,000m, and 10,000m. Note that your degree of offset will be directly proportional to the distance of the leg. The number of digits in the numerical location must be even: 0, 2, 4, 6, 8 or 10, depending on the desired precision. Even if you have your go-to method for navigating already, give MGRS a shot.
