I want to know the answer to the following question:
What was mounted on poles by forces?
All the background I'm provided with is that "As aircraft started to be used against ground targets on the battlefield, the AA guns could not be traversed quickly enough at close targets and, being relatively few, were not always in the right place (and were often unpopular with other troops), so changed positions frequently.". Is that enough to answer the question?
Answer: no
