Other than the requirement to place a sniper in a hex with a positive TM with no enemy currently occupying the hex, must a sniper be placed within the specified set-up area of its forces in the scenario (after set-up is finished and play has started)? There does not appear to be such a restriction. For instance, could it even be placed behind enemy lines? This seems to be possible. Would appreciate any guidance from experienced players of LNL Tactical. Thanks.
