An early model British Mark I "male" tank, named C-15, near Thiepval, 25 September 1916. The tank is probably in reserve for the <a href="https://en.wikipedia.org/wiki/Battle_of_Thiepval_Ridge" class="extiw" title="en:Battle of Thiepval Ridge">Battle of Thiepval Ridge</a> which began on 26 September. The tank is fitted with the wire "grenade shield" and steering tail, both features discarded in the next models.
