Hi Ade,
yup the trench tiles are pretty well finished and the placing of the target sites is going well, but I am having to update the default map as I go along because the geography of the Somme and other western front areas is not accurately modelled. I have pretty well placed all the sites north of Arras and several of the southern areas too. I am also putting in targets at the main towns in the area, like Leon, Arras, Vimy, Lille, St Quentin, Mons as well as the airfields you indicated on your map, I will drop it over as soon as I have completed positioning the sites to see if you are happy with the choices of targets. Once you are happy them I will start populating them with individual targets items.
cheers,
Pobs
