Royal Artillery Operation Instruction No. 5 dated 28th July 1941.

This two-page document was concerned with the engagement of hostile reconnaissance aircraft.

Recent experience had shown that the first targets of airborne attacks had been the anti-aircraft gun positions, discovered in previous enemy reconnaissance flights.

So that newly occupied gun positions were not disclosed before a main attack developed, detachments were urged to give particular attention to concealment and that only those guns which had previously engaged enemy aircraft would in future engage single enemy reconnaissance aircraft.

The gun sites were identified in Reykjavik as follows:-

Heavy Anti-aircraft – GROTTA, PIMPLE HILL, SKELETON HILL, GARDAR.

Light Anti-aircraft – CORBETT CAMP.

Kaldadarnes gun sites were as follows:-

Heavy Anti-aircraft – AUDSHOLT.

Light Anti-aircraft – AERODROME (two Bofors).

All Anti-aircraft units would take post on the receipt of air raid message “Yellow” but guns other than those detailed above would not engage a single aircraft unless it was at such a height as to suggest a good prospect of its destruction. This decision was the responsibility of the Section Commander or the nearest Troop Commander in the case of the Light guns.

If the aircraft is identified as a single enemy, Detachments other than those above would minimise their movements so as not to draw attention to themselves, or disclose their positions.

New gun positions were to be dug as low as possible, consistent with the operation of the gun and supporting instruments, as a means of concealment.

In new camps, huts would be laid out and painted to make them as inconspicuous as possible. Some could, it was suggested, be painted to resemble farm houses or villages. In such cases G.S.O. (Camouflage) should be consulted before work commenced.
