    If the angle of the legs from the barrel is anything to go by, then they have not dug in and will shift when the gun is fired, throwing off the sighting.

      Back in the day when we fired the Brandt 120 mm, If we were firing with the carriage removed (Mortar could be fired with carriage attached to bipods, which made it quicker to get into action, but was a **** to traverse because you had to lift the weight of the carriage aswell as the bipods/barrell) the the No's 3+4 would keep a foot on the bipod shoes and this would stop it from jumping. Whereas when the carriage was on it weighed it down so it was'nt necessary to stand on the shoes.
      But there's no danger
      It's a professional career
      Though it could be arranged
      With just a word in Mr. Churchill's ear

        As you said, it's simply that the ground seems to be too hard for the bipod legs to stick into the ground.
        In that pic, the ground inside the ring of sandbags seems to be sand laid on top of gravel (look at the lying soldiers left foot there is a mark on the ground from his toe) so if anything the ground is too light to take a firm hold of the bipod.

          I'm surprised that the are not using active ear defenders.

          The latest active types block out the thump very effectively without any loss of normal situation awareness. You can also get on with the job without having to play ostrich every round.

          I doubt that they were in the middle of an urgent FFE. If so, I would expect rounds in hand ready to follow the first one into the tube.

            It is definitely a prepared mortar position (Hesco)

                    You can tell from the angle that

                    a late popping illumn has been fired

                    the LPI's hang over the target for up to 5 hours and illuminate on command

                    we ahvent got them yet- but the Yids were using them back in the leb in 98-01

                        The position could double up as a nice campfire circle for the cold nights! A few spare charge relays would make handy firelighters and they could munch a few smores while waiting for Hedgie's illum bombs to light up.

                        I'm curious as to what they lay onto? That blast wall is so close that using an aiming post or a mark on the wall would be very innaccurate. Other options might be a paralleloscope or a GAP on the distant hilltop if there is line of sight over the wall. Does anyone know?

                          You will find that they have an aiming post or aiming mark attached to the 4 cardinal points
                          in that position;

                          American mortar teams place their aiming posts between 15 and 20 feet out from the Mortar;

                          if they cant find the required distance they alternate and use what are known as alpha tables

                          or A Dog tables as they are better known- the A Dog tables calculate the difference in the different tabulations

                          when an aiming post cant be put in at either of the recomended distances-


                          You will note that they are apparantley at an altitude and as all us Mortar men know - one of the factors that influence the flight of the bomb is altitude- therefore the A Dog tables can also tabulate difference because of atitude- humidty etc etc.

                          the reason they are called A Dog tables is the person who formulated them was a Marine Corp
                          Seargent Major called Alan Doogan aka A Dog.

                              The ground looks like its hardcore (broken rock, typically 50mm diameter) that was brought in to level the site and no consideration was given for the mortar base. While the hardcore might be firm, it might also be too firm and be difficult to bed things in.

                              The sand is to level things off and fill the gaps between the stones to stop the tri-pod shoes and base plate being dented / cracked / damaged and give a limited amount of squeeze.

                                Thanks for that.
                                I'm surprised to hear that an army that uses technology so much in other areas is using tables as their primary method of calculating MET corrections.
