“ absence of the normal; presence of the abnormal ” (what ’ s missing / what ’ s new) Look out for the following indicators: COLOUR – Unnatural colours or colour change. The difference in colour will depend on the length of time since emplacement, often clearer 24-48 hrs after emplacement. TRANSFERENCE – Soil, sand, foliage and other debris deposited in places where nature would not cause it to be. REGULARITY – Geometric shapes and strange angles which do not naturally occur.
FLATTENING – Foliage, grass etc flattened by humans/animals reflects the light at a different angle. DISCARDABLES – Items left visible by the INS when placing IEDs such as cigarette butts, bits of wire or tape. DISTURBANCE – Movement of soil, breaking of foliage and placing of items in an unnatural way to attempt to cover sign. “ absence of the normal; presence of the abnormal ” (what ’ s missing / what ’ s new)

PRACTICE There ’ s now a chance to practice looking for the Ground Sign in a number of pictures. Not all the pictures actually have Ground Sign in them – the first two slides are an example of one with and one without – the answer is revealed each time on the next mouse click. The phrase ‘ No known indicators ’ is used for pictures without Ground Sign – because we don ’ t know for certain that there was nothing there. In other words, if you see something that you think is suspicious in a picture then you are not wrong. After the two examples there are two presentations with 20 pictures each – the first is easy the second is more difficult. For each picture you should identify any Ground Sign before clicking for the answer.
