Hi,
It is not a major game braking thing or anything, but currently you can deactivate mines from around 2 meter distance. I would really like to see that reduced to realistically arms range. The mine will not go off when you are within 1 meter so it can easily be reduced I think.
Currently you can deactivate AP mines in crouch position. I really like to see it only possible in prown position and within 50 cm range of the mine for immersion purpose. The AP mines need to be more dangerous and tricky to deactivate.
