Right. For example, English Longbowmen were often peasants/woodsmen that started training with a Longbow when they were very young. They brought their Longbow with them to war. I would assert that the Longbow we definitely a valuable piece of gear.
Longbowmen are a special case as the king wanted to make an army of longbowmen, so they were required BY LAW to train and have a bow.
Also, a longbow isn't that expensive or difficult to make.
The most expensive piece of wargear is BY FAR the armor.
