Leap-frogging is a navigational technique used to walk on a bearing in poor visibility where absence of land features


Leap Frogging

Leap frogging is a simple concept and accurate for walking on a bearing, but those involved need be given clear instructions about how it works.

Picture the scene; you have some featureless ground to pass over, and it's misty, with visibility down to 30 metres, and you have to walk several hundred metres. You know where you are and have taken a bearing from your map, eyed it up and know the direction in which to travel. But you know that attempting to walk on a bearing, i.e. whilst looking at the compass, is pretty much impossible to do accurately. The solution; leap frogging, so long as you're not walking alone!

Here's how it works. Having got your compass ready with the bearing on which to walk, send one of your companions walking ahead, with the clear instruction to keep turning around and stop when you are about disappearing in the mist. Once they stop, you need to check whether they are exactly on the bearing you've taken. The chances are that they's not, so hold your left arm up if you want them to move in that direction, and vice versa. \when they are in-line with the bearing, bring your arm down for them to stop. Walk towards them, but of course you don't need to walk on the bearning.

Once at your companion, repeat the process. Send them out ahead, direct them left or right, then walk towards them. Repeat as may times as required until you reach your target or attack point. It's that simple.

Experience has shown that some people grasp the concept quicker than others. Some just keep walking and don't stop; others don't understand the moving left/right part. Be sure to give a good explanation and get your leap frog buddy to explain the process back to you before they set off.

Navigator directs the "frog" to the right to keep on the bearing.
