2nd Bn, 56th Arty, 1966-68 (Source: Richard Tracy) The commo room in the New BOC building: if you look closely, you can see a German civilian telephone, for administrative calls; a field phone (TA-312) and switchboard (SB-22), for patching secure landline and radio calls into our internal telephone system; several UHF radios inside the commo van (accessible through a warehouse-style roll-up door); plus the normal assortment of office equipment (including a hotplate). This was a major improvement over the Old BOC set-up!
