6.4.5 Rough Terrain (A6/1) 6.4.5.1 Description: 6.4.5.2 Results: Page 26 of 77 A 100m strip of heavily vegetated/wooded land on a side slope was set out. A simulated minefield was laid in the first 5m and a tree was situated in roughly halfway along the strip (~300mm thick trunk). See figures 6.20 to 6.23. Aardvark started flailing at 200m/hr this was flail speed was cutting too deep, so after a few metres the speed was increased to 300m/hr. This changed the flail depth from an average depth of 275mm to an ayerage depth of 163mm. The angle of the side slope at various points is as follows. • At the end of the minefield = 10º 10’ • ½ way across = 5º • ¾ way across = 14º 14’ 6.4.5.3 Comments & Observations Aardvark cleared the minefield and reduced the 2.5m high foliage to fine mulch. It knocked the tree over and reduced half of it to mulch. The TMA-3 AT mine simulant in figure 6-23 has been hit several times, one of the fuses has been split. It was considered that this would have probably detonated or been incapacitated. DERA/LWS/LSAA/TRD000603/1.2

<strong>Aardvark</strong> started flailing at 200m/hr this was flail speed was cutting too deep, so after a<br />
