The presence of generators would suggest searchlights.I did not see evidence of any large gun emplacements,but they would have been in short supply at the time,small arms and rifles would be the limit.Another possibility would have been a barrage balloon,but these were nearer to towns or important sites.So,it's looking like an observation and searchlight post.The location is off the A56 by-pass as on the attached Google Earth grabs.
