I just had another look at this and the end of 1.2 on page 13 reads that shooters cannot claim use of shield. Whilst I agree for missle weapons that need two hands ( bows, crossbows etc) I would have thought that darts and to a certain extent javelins could claim shielded. Slings (and atl atl?) may be debatable due to the space needed to wind up the shot. what do you think?
Leading on from this is shooting from shield walls, eg darts from legionaries and Javelins from Daylami. Does shooting remove shield wall or is there a strange situation where shield wall exists for hitting but unshielded to save? My thought is that these troops get the full shield wall benefit whilst shooting.
