Couple reasons, as I see it, why we still use bullets.
Number one, as someone else mentioned, is the power source. The weight of a weapon is VERY important in choosing what will be the standard issue
weapon. The reason we switched to M16s from M14s was because of weight. Weight of the gun, and of the larger ammunition. There is also the recoil
factor as well.
There isn't any batteries currently made that can store the kind of energy required to supply any decent number of "shots" from an electricity based
weapon. Also a factor is how volatile most of our current high capacity batteries are. War is tough on tools, and people probably don't want batteries
catching fire or exploding all over soldiers.
Then you have to recharge, or replace the batteries. This brings more on-site equipment, and you are going to have to have a local energy source to
Also, while a laser may be good at cutting, it's not so great at causing catastrophic damage to tissue. With a military weapon your goal is to kill
the enemy in as little time as possible. Putting a tiny neat little hole through him won't accomplish that, unless you specifically hit the heart,
Where as with a bullet, there is a ton of damage done to the body. It doesn't put a nice neat bullet shaped hole in someone, is tears them apart and
opens up a large cavity inside them, damaging organs and tissues a lot farther away from the point of impact than a laser would.
Until we make huge advancements in battery technology, I don't see lasers being used for infantry weapons. Even then, it seems something like coil
guns would be better. It still uses a projectile, but uses magnets to propel it. If you google them, you can find quite a few really cool designs.
They are, for the moment, more useful than rail guns on the small scale, because rail guns tend to destroy the rails after a few shots, where as coil
That is a pretty cool looking laser gun though!
