Night vision was destroyed by the white magnesium light of the flares and, when the visibility was reduced in haze, the sensation was like being inside a goldfish bowl. Nevertheless, it was occasionally possible to attack even tank-sized targets. Larger objects such as bridges with a line feature to follow in to the target or ships with a wake were much easier and splash target results were quite good.
A stick of Lepus helped to provide a roughly horizontal visual reference but one or a pair together were no help at all.
Not the best way to survive against a defended target but it gave a 24-hour capability and, with the benefit of surprise, provided a worthwhile option.
