Check out some of the rather wonderful drawings here - http://www.gaddgedlar.com/bannockburn_2003%20Kit.htm
- check out the "highlanders and islemen" images & text. If gives a wonderful impression; axes, spears, swords. Most people would have a 'side arm' or camp knife. A bow is possible, but likely not for combat - gallowglass tended to hire 'horse boys' to look after their horse and equipment. In the 16thC, they are said to fight alongside their master, using a bow. usually, javelins are thrown by someone with a shield, not someone with double handed axe. You can't hold and axe and three javelins, but you can hold a shield & three javelins. So, some guys likely had axes, others had swords.
