The Avalonian soldiers who are given outpost duty aren't even close to being expert archers, but the outposts have been constructed with arrow loops to allow Forestmen to position themselves inside the fortification if necessary.
Built for the Watchtower Challenge of the Eurobricks Castle Community Build. I was going to go for a traditional stone watchtower, but the technique I use for the walls used up too many tiles and I got stuck at this height. Then I tried a tree-based watchtower for the Forestmen, but maydayartist had already made an excellent one of those that I knew I didn't have enough leaf pieces to come close to. So I combined the two ideas into a sort of hybrid outpost, with the Forestmen in the trees doing the watching and the Avalonian soldiers manning a short guardhouse.
