Manual clearance is legit poking around with a tent peg / bayonet until you find a mine. Survey can give locations of the obvious ones, but they always miss a few. Then you have to identify which sort it is, and remove it without setting it off.

According to my old boss, if you survive the first few lifts you'll survive a long time, and the pay is amazing. But that everyone who works in EOD is mad.

I looked at him straight-faced and he laughed and said "including me".

We have robots and mine flails now, in rich countries, but someone still has to poke around afterwards.
