The two other section groupings were also modified; the assault team/support team grouping now had the Charlie fireteam consist of the section commander, a rifleman with UGL, and both section gunners, with the Delta fireteam consisting of the section 2IC, both section marksmen, and a rifleman with UGL. The rifle group/gun group organisation was replaced by a fast assault/fire support grouping where the Charlie fireteam consisted of the section commander with UGL and a rifleman, while all remaining personnel formed the Delta fireteam. Trench clearing and house clearing groupings remained unchanged. Some units operating in Afghanistan carried on using the L7A2 GPMG as the section machine gun or included it as an additional weapon on the scale of one per fireteam; in the case of the latter, this meant that only two L85A2s (at least one of which was fitted with the UGL) were carried per section. The 84mm AT-4 (L1A2 or L2A1) and then the 150mm NLAW replaced the L1A1 94mm HEAT rocket as the section anti-armour weapon, though carrying arrangements were essentially unchanged; the Javelin can also be carried for anti-armour capability. The L128A1 12 bore combat shotgun was introduced for use by the section point man, with this position subject to rotation within the section to avoid excessive stress for individual soldiers.
