There is really only one advantage to a cross bow and that is, of course, you dont have to draw the bow string. The doing of which can give away your position to an enemy, or the game you are pursuing. Additionally you dont have to draw and hold the bow string either waiting for an enemy to get into a better killing position.
This is a real plus because, and while Ive never used any kind of bow in combat, I have lost game from the drawing of the bow string of a regular bow. Either from noise or from the strain of maintaining a full draw. When hunting game this can be reduced by hunting from stands but in combat this, of course, cant be counted upon. The actual sound made by either bow when the arrow/bolt is released???? I would rate the cross bow as being noisier by far. Not only do you have a trigger release mechanism making noise I have found cross bow string noise dampeners to be less effective on crossbows, "another reason for keeping your distance short".
On the other hand you cant fire as many projectiles with a cross bow as you can a regular bow. I must say when comparing the two, and all the kills I made with each, I found the short,heavy cross bow arrows and bolts to be absolutely devastating on game. I always had better luck with expandable broadheads on my cross bow projectiles, while with my regular bows Thunderhead 125s worked fine. With the cross bow, and if I knew I made a good shot, instead of waiting 30 mins to collect my game I would track it down sooner. The point I'm making is that the cross bow seemed to inflict wounds which caused shock and catastrophic blood loss much sooner then regular archery gear, and, shot the projectile thru the beast that is a requirement for a faster kill. Both however are slow killers compared to HP rifles. Bows kill by bleed out and shock.
For a young warrior taking up the sport would, I believe, be a fine thing. Not only can they connect with warriors of the past but they would be developing a useful skill, most of all, if they take to the hunting fields with it. Hunting game with a bow will teach many useful skills to a youngster who plans to become a soldier. Among them discipline, maturity, wood craft, tracking, weaponry, ambush skills, and the self dependence that is a requirement for good leadership.
Thank you.
