under 50 yards or clearing trenches or buildings a burst of 556 will absolutely do the job and if hes bleeding on the ground but reaching for his gun after give him another burst. ukraine war is my proof. so will 545 and so will x39. you have a 30 round mag in your gun for a reason but regardless situations like these are quite uncommon for the average soldier being rotated at the front, usually more common during events like the siege of bahkmut.
