I would say a trained army. Even a trained team is simply too small for such a large area

3 - According to the RPG book Tails of Equestria, shield spells are very common and pretty easy, and we’ve seen Sweetie Belle use a basic, localized shield spell to ward off Flyders. The question comes in if the shield is strong enough to ward off an area effect, tremendous blast, or high velocity.
 
2 - I get the impression that Accelero is more generalized and not even originally intended to be used on an individual living thing. It can also be theorized that the smaller the object the easier it is lifted and cast, and presumably the faster it can be thrown.
 
1 - The information seems to be labeled “1.2”, so the other pony types probably have their own set. But I have a hunch that firearms wouldn’t deal as much damage on a pony as people think based on some of the punishment we’ve seen them take and the distinctly different laws of nature they seem to follow.
 
As per my Superstring Theory to Equestria, which explains everything from Pinkie Pie breaking the 4th wall to Pegasi walking on clouds, and Alicorns raising the sun and moon, ponies (those best able to do this, the Earth Ponies specifically) are able to manipulate their “mass” and materials around them, which would allow them to resist the normal damage and penetration afforded to projectiles, including firearms.
 
On further, some (notably Pegasi) would be capable of a similar manipulation of the atmosphere, allowing them to control weather, create storms, kick lightning out of clouds, build structures out of clouds, handle solid objects on clouds, fly at incredible speeds and impossible heights, and even shatter the light spectrum. One can only imagine the multitudinous applications that brings to dealing with a non-magical Human armed with a gun.

Nice but a trained team would take out all of Equestria.

Questions:  
  • What about earth ponies and pegasi?  
  • Why accelerate the bullet back as opposed to telekinesis or magic blasts? (We’ve never seen telekinesis move things at bullet speeds and Accelero only seems to effect the user.)  
  • Are shield spells common enough for this viable? (The only ones who used them on their own were magically prodigious/knowledgeable main characters.)

Well, without greater context, it’s difficult to tell if the artist/writer genuinely believes that most all Unicorns are perfectly capable of doing this ad firearms are that weak…
 
Or if the information in the post is designed to mock PSAs that try to keep the informed calm under such circumstances with confidence, and the creator is absolutely aware of the potential absurdity.

MAYBE if magic is something they’re naturally skilled at and have had lots of training specifically to deal with this kind of threat, but you’re average horn-head wouldn’t stand a chance.

Unrealistic, ponies wouldn’t try to kill the human.

What kind of idiot tries to kill ponies? You’re supposed to hug and pet and hold them and ruffle their chest and belly floofs.
