In wftf you can use a knee pad in free position (there is no restriction on size shape etc) and kneeling roll only in kneeling lanes (max 18cm diameter but we mostly use around 10-14cm). You can’t use a seating cushion on kneeling position. Honestly I don’t understand the need for so many classes but if you like it…
Just for clarification, you are referring to WFTF matches, not AAFTA matches shooting in WFTF Division.
And we don't have that many classes (yet).
*warning - attempted humor to follow. please don't read any farther if you are soft, easily offended or a cranky old fart*
We have the WFTF Division which mostly matches WFTF rules.
Then we have Hunter Division for the people that can't get off of the ground without help, or who think FT guns look weird and want to shoot "normal" looking guns at American Freedom velocities. Because this was too easy, these shooters were allowed to use the same scopes as everyone else but had to turn them down to 16x. (There is a push for a new class that would basically be Hunter class without the scope restriction because a lot of these guys don't like spending thousands of dollars on a scope and not being able to use all of it).
Then we have Open division, which hardly anyone shoots. Open div is basically WFTF rules with American Freedom velocities. And for some weird reason, this wasn't easy enough so they also allow Open div to use leg straps and thigh rests. Not sure why people don't shoot Open division. As I write this, I'm not sure why I don't shoot Open Division.
And each division has a PCP and Piston class.
Unlike the rest of the world, we unleash all 3 divisions on the same course simultaneously. And that's where the problems begin. Some shooters think they are competing against their division. Some shooters think they are competing against the other divisions. Some of those shooters think that the other divisions have an unfair advantage, even though they aren't actually competing against each other. So they try to change things to make an "even playing field" (even though it's actually 3 different fields, each with its own elevation). So they try to change their division, or the other divisions, or make a new division. All so they can beat someone who is shooting with different rules at the same time as they are. It looks weird when you write it all down, but trust me, we are Americans and we know what we are doing.
So now you know why we have so many divisions. We are constantly looking for ways to get fewer people to shoot field target so that we can complain about the poor participation in field target. Next, I'll tell you all of the ways that American football is better than soccer.
