That is the Wars of Independence, though, not the clan wars. Equipment was significantly different. In the clan wars, great kilts were worn, and basket-hilted back-swords or broad-swords were mainly used (along with dirks, pistols, muskets, and claymores). In the other, some odd looking Irish thing was worn (not like the movie), everything was a lot more medieval, and claymores were the main weapon. The clans were also a lot different.
