Sorry can't help with that, but it does remind me of a Falklands
story. In the fighting around Mount Tumbledown a young lieutenant
was tasked with clearing a string of Argentinian machinegun nests.
he did it using a lot of Milan Anti-tank missiles at about £10,000
a shot!!
He said after, 'I was told to clear them quickly, not cheaply'
In other words, If you have the kit, & it does the job, use it.
