Section III. DETECTION-GRADE 5 



87. General 



During grade 5 detection training maximum ef- 

 fort and imagination are used to conceal targets. 

 Targets must be made as difficult to locate as is 

 tactically reasonable. 



88. Ordnance— Grade 5 (Table 1) 



a. Buried. Repeat grade 4 procedure, except seal 

 around the cover-plate so that there are no 

 visible traces. 



b. Hidden and Elevated. No portion of the tar- 

 get is visible from the direction of approach. 



Section IV. TUNNELS, 



92. Scope 



This training exposes the mine and tunnel dog 

 team to those classes of targets, other than ord- 

 nance and tripwires, that they may expect to en- 

 counter on operations. This training is discretion- 

 ary and should be adjusted according to antici- 

 pated operational needs. 



Note. The training outlined in paragraphs 92 through 

 107 is conducted concurrently with grades 4 and 5 de- 

 tection training. 



93. Tunnels 



This term tunnels refers to all hole-like targets, 

 such as tunnels, bunkers, mantraps, and covered 

 foxholes or spiderholes. For training purposes, 

 the above can be simulated by digging holes 

 about 1 foot wide and 1 to 3 feet deep, and cover- 

 ing them with a light screen of grass, twigs, and 

 leaves. Dogs should respond as they do to other 

 type targets. It is desirable to disturb the earth 

 in the hole before each use. An article of re- 

 cently worn clothing may be placed in the hole 

 before it is used. 



94. Caches 



This term refers to any item(s) of military equip- 

 ment hidden at, above, or below the ground. 

 Typical items are: weapons, ammunition, or web 

 gear. Food stuffs may also be stored in caches. 



95. Procedure 



a. Introduce tunnels and caches by integrat- 

 ing one of them on a grade 4 lane. 



89. Tripwires— Grade 5 (Table 2) 



Same as grade 4, except that vines may be added. 

 Use maximum ingenuity in tripwire settings. 



90. Procedure 



a. Lanes should be 1,000 to 2,000 meters long. 



b. Some lanes should be run with only one to 

 three targets. 



91. Performance Criteria 



Same as required of handler and dog in grade 4 

 detection training. 



CACHES, AND DECOYS 



b. Periodically, add one or more tunnel- or 

 cache-type targets to a problem. 



c. For those dogs that fail to recognize these 

 items as targets, or fail to respond to them, the 

 orientation procedure may be necessary. These 

 dogs can be taught to orient on these targets as 

 they did on the feed pan. 



96. Decoys 



a. Although the mine and tunnel dog is not 

 expected to perform the scout dog function, and 

 indeed must restrict its attention to its immedi- 

 ate environment, personnel will be encountered 

 on some operations. The dogs must be taught to 

 alert on an occasional decoy, and that they are 

 rewarded for doing so. 



b. The instructors must take care that decoys 

 aren't used too often. Since a strange person is 

 more interesting to a dog than a mine, the pro- 

 cedure must be used only to the extent that the 

 dogs are aware of decoys. Otherwise they will 

 neglect their primary task while searching for 

 the decoys. 



97. Procedure 



No special training is required. On every third or 

 fourth problem, a decoy should be placed toward 

 the end of the lane, 10 to 15 meters off-trail on 

 the upwind side. Nearly all dogs will give an alert 

 on picking up the scent.
