Klineman Halpen (Tim McInnerny) uses a Bruni ME-8 Police (presumably standing in for a Walther PPK) to threaten the Doctor (David Tennant) and Donna Noble (Catherine Tate), before he becomes an Ood in the episode "Planet of the Ood".
M4A1 Carbines are used by the Ood Operations security forces during the episode Planet of the Ood. The M4A1s are being seen used with Beta C-Mags, ACOGs, tactical lights, Eotechs and front grips.
UNIT soldiers, including Private Carl Harris (Clive Standen) and Private Steve Grey (Wesley Theobald) are seen carrying Heckler & Koch G36C's as their primary weapon in "The Sontaran Stratagem" and "The Poison Sky". They are rendered useless by the Sontaran's Cordolaine signal, which excites the copper atoms in bullets and causes them to expand in the gun barrel.
UNIT soldiers use M4-type rifles similar to the Olympic Arms K23B Tactical in the episode "The Poison Sky", during the assault on the ATMOS factory. They are said to be firing steel-jacketed rounds, due to copper-jacketed rounds being rendered useless because of the Sontarans Cordolaine signal.
