Navigate from one point on the ground to another point while dismounted with AN/PSN-11 (PLGR)
TASK: Navigate from one point on the ground to another point while dismounted with AN/PSN-11 (PLGR).
TEST CONDITIONS: During daylight, on a land navigation course, given a 1:50,000-scale military topographic map, AN/PSN-11 (PLGR) (verified PLGR setup), a compass, a coordinate scale and protractor (or GTA 5-2-12), a pencil, a designated starting stake, and an 8-digit grid coordinate to subsequent location stakes (requirement sheet).
1. Determine the 8-digit grid coordinate of the starting stake to within (plus or minus) 50 meters of its location (the grid zone designator must be included).
2. Locate three out of a possible three stakes by using land navigation techniques.
3. Record the identification number of each stake.
4. Complete all performance measures within the specified time determined by the EIB board (2 hours).
SOLDIER’S MANUAL CROSSWALK: This task is based on task number 071-329-7017 in STP 21-24-SMCT and FM 3-25-26.
EQUIPMENT REQUIRED FOR POINT: AN/PSN-11 (PLGR), lensatic compasses, 1:50,000-scale military map sheets, coordinate scale and protractors (or GTA 5-2-12), field tables, sample stake, lane stakes, operations tent (at start and finish points), lister bags (or other water container), radios, control vehicle, first-aid equipment and supplies, and FB Form 20-R.
NOTE: In order to administer this station, members of the EIB committee must hold certification from the EIB board. Do not use a land navigation committee unless each member holds EIB board certification or at least answers to the EIB board.
SITE SETUP: Ensure the course conforms to the standards described in the following general instructions section. After candidates are briefed, they should move to their assigned starting stake. There they must plot the 8-digit grid coordinate of that stake. The candidates then proceed through the course, following the instructions provided on the FB Form 20-R (EIB Test Requirements Sheet, Day Land Navigation). See Figure 5-3 (page 5-7) for an example of a completed requirements sheet for this task summary.
GENERAL INSTRUCTIONS: Each candidate must negotiate and successfully complete the day land navigation phase and night land navigation phase. For retesting purposes, the day and night phases each are considered one point. Candidates must satisfy all performance measures to receive a passing score on each point.
Brief all candidates on their responsibilities to other candidates in need of first aid. A candidate who fails due to having rendered aid to another candidate can retake the test without penalty.
The local EIB board ensures that the candidates can complete the courses within the time specified in the standards. FM 3-25.26 recommends one hour for up to a 3,000-meter lane (trails). Base the time standards on the validation of the two courses (day and night) conducted by SMEs, the number to be determined by the EIB board. The SMEs cannot have participated in the design of the course.
COURSE LAYOUT: Ensure the day land navigation course has sufficient stakes to allow candidates to use several lanes at once. Each lane should be at least 3,500 to 4,500 meters in length and include at least two directional changes and three legs. No stake should be closer than 100 meters to another stake. Mark the stakes clearly using signs.
NOTE: When constructing lanes for an area all lanes should be no more than 500 meters in total distance from the shortest lane to the longest lane.
The signs for both day land navigation course and night land navigation phase should be 12 inches by 12 inches; half of the sign is white and the other half is international orange. Stake the sign into the ground so that the bottom of the sign is neither less than 5 feet nor more than 7 feet above the ground. Each sign must have a clearly identifiable unique letter or number on it.
INSTRUCTIONS TO CANDIDATES: Say to the candidates–
“Let me have your attention.
“At this point you will navigate from one point on the ground to another point while dismounted (day). This will test your ability to navigate from one stake to another stake during daylight hours with the AN/PSN-11 (PLGR), a map, a compass, a coordinate scale and protractor (or GTA 5-2-12).
“At your starting stake, you will determine and record the 8-digit grid coordinate of the starting stake to within 50 meters of its location. Then you will receive an 8-digit grid coordinate to Stake 2.
“You will complete the requirements for locating this stake and then proceed to the next stake. At stakes 2, 3, and the finish stake you must identify and record all stake identification numbers. We will post identification numbers on 12-inch by 12-inch signs painted white and international orange. The signs are attached to stakes 5 to 7 feet above the ground.
“You will receive an AN/PSN-11 (PLGR), a map, a compass, a coordinate scale and protractor, and a requirements sheet. Do not begin this point test until we tell you to do so. Once all candidates have received their requirements sheets, I will announce ‘BEGIN.’
“At that time, you will move to your starting stake. Your time starts when I again say, ‘BEGIN,’ and it ends when you report to the scorer’s tent located at _____ (EIB board determines location).
“At this time, you will have _________ (EIB board determines time) in which to complete all requirements and report to the scorer’s tent located at ____ (EIB board determines location).
“If you do not meet the requirements, if you lose your requirements sheet, or if your requirements sheet is not readable, you will not receive a passing score.
“All work and navigation are accomplished by the individual candidate, not by buddy teams.
“Your present location is ________ (8-digit location).
“The course boundaries are (North)_______, (South)______, (East)______ and (West)______. The starting points are located at _________ and ________ (include the location of the starting stakes)”
Discuss the appropriate safety precautions and the candidates’ responsibilities for helping injured candidates.
“What are your questions?”
If anyone has questions, repeat the instructions but do not elaborate on what you have read.
Pause five seconds and then say–
