So, recently, I have been spending a chunk of my shifts in the tent that holds biathlon equipment. AKA RIFLES! And in this time I have learned a bit about the sport.
In the paralympics, this means there are different variations. Standing biathlon, sitting biathlon, and visually-impaired biathlon.
The first thought I had (in my head of course, didn't want to look stupid haha) was how dangerous it must be for people with limited or no sight to shoot a gun. duh. Realizing how stupid my thought was, I discretely looked into it and figured it out. Laser rifles. No ammunition, and based on sound. COOL.
Here is a link I found that kind of explains it a bit more.
