You've got to protect your kids from all harm, but that's not why this stroller has a rifle and a shotgun attached. Competitive practical shooters, particularly those in 3-gun competitions (rifle, shotgun, and handgun) have to transport a lot of gear around. Some have found that it's easier if they modify jogging strollers to carry their equipment. You can see more examples at the link.

Children don't ride in these. Many of the competitors who use these don't have kids, or don't have kids small enough to ride in a stroller anymore.
The reason for the jogging stroller? They can be found for around $25 all day long on Craigslist AND the cheap ATV gunmounts fit on the tube steel frame. They handle crappy terrain and mud well. And, they fold up. Compare that to around $100 for a garden cart or ATV Radio Flyer wagon to haul all your rifles, hundreds of rounds of ammo and other gear and you'll see why these old jogging strollers are the pack mule of shooting competitions.
