OK Bone question. I'm on the Junior Leaders course with cadets and need to be able to operate in a tactical environment at night.
For night navigation, is a blue filter on your torch suitable or does it have to be green?
A word from the wise, and a voice of experience:
I once used blue light for navigation in South Armagh, for those familiar with "Bandit Country" you will know where I am going with this one. Water features are marked in blue on your maps and South Armagh is notoriously boggy, letâs just say, the blokes in my team were less than happy with me by the end of the patrol.
All coloured light has its disadvantages for night navigation, as mentioned red light hides contour lines; blue hides water features, green hides forestry blocks etc.
Best advice, study the map in detail before setting out, rely more on your route card (providing it has a lot of detail on it) and trust your compass, always pace out the distance between legs and confirm this with a check pacer.
