MASTER GROUND
SIGN AWARENESS
So what am I looking for?
“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.

PRACTICEThere’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.
