If shooting 50-100 yards then breathing does not matter that much but to regularly knock down targets at 200 yards plus (especially over 300 yards) you really need to pay attention to your breathing. Personally I always found the Fire Trench to be the most stable positions, especially if you 'cheated' and jammed the base of the magazine into the ground. Then it is breath in, out, in, hold, fire and repeat to get really accurate fire...
Of course I think the game exaggerates effect a bit because the enemy are generally pretty close to you rather than been 200-400 yards away on average...
