Reinforced field construction is shown with thinner lines to distinguish it from permanent construction. The columns distinguish planned, under construction and completed installations. The numbers attached to anti-aircraft symbols indicate the number of installed guns.

Infantry installations; artillery installations, with M.B. meaning naval battery and H.K.B. Army coastal battery; tunnel installations; anti-tank walls; naval direction-finding posts; fire-control posts; anti-aircraft artillery, including 2 cm, quadruple 2 cm, 3.7 cm and heavy weapons; battalion headquarters; regimental headquarters; command posts; air raid protection installation; signals installation; fuel installation; electricity installation; minefields.

Note: Because the personnel units of the Army coastal batteries and divisional artillery have changed, and will continue to change, owing to the rotation of reliefs with Alderney, the batteries are given fixed geographical names on the construction maps. Unit numbers from the previous report are still included in brackets for comparison.
