Here’s an training acronym that I was wholly unfamiliar with until recently.
F.O.R.S. Front Opposite, Rear Same
This is in relation to windage and elevation adjustments using iron sights. I’ve understood this concept for a long time but have often wanted for an easier way of explaining it. F.O.R.S. does that job beautifully.
For those not in the know, in the case of a front sight, it should be adjusted in the OPPOSITE direction that you want to correct for.
For instance, if your point of impact is 6” high and 6” left of your point of aim, then your front sight should be raised in order to correct for elevation and drifted to the left to correct for windage. Opposite of where you want the bullet to impact. Doing this will bring the impact down and to the right.
Conversely, if you’re using the rear sight to correct the point of impact, then the sight should be adjusted in the same direction that you want to correct for. In the above scenario, 6” high and 6” left, then you would lower the rear and adjust it to the right to correct the point of impact. The SAME direction that you want to bullet to impact.
This is an aspect of shooting that most new shooters and even some seasoned shooters have trouble comprehending.
There is an Iraqvereran8888 YouTube video, “How to adjust iron sights”, that explains the basics of sight adjustment using a very simple fixture that uses sliding blocks and a laser pointer that helps to visualize all of the concepts involved.
