My section got tasked one day, with way too little notice to do any real liaison or planning, to act as pathfinders for a few US UH60s lifting a Canadian course, possibly CLC, from somewhere out on the plateau on the far side of the Black Forest to an area just south of Lahr. We zipped out to the PZ and had a quick chat with the UH60 guys and troops then had to head off straight-line non-tac, with one of the DS in my back seat, in order to beat the UH60s back (much faster than us) and FIND an LZ before we could direct them into it (nobody had planned ANY of this, just, apparently, phoned a UH60 unit and asked for a ride somewhere and then called us). We found a field, but didn't have time to inspect it closely before radioing a grid no more than about 30 seconds before the UH60s arrived. The farmer's freshly-cut wheat or whatever it was that was laying on the ground pretty much all disappeared. We only had a few minutes to find another field before they returned with the second lift. Every single field that we checked had either a cut crop like the first or one still standing. We were getting pretty desperate, as the UH60s were getting close, when we finally found one with nothing but stubble in a corner between a railway line and a bundestrasse overpass. GREAT - out went the grid, again, thirty seconds later the UH60s landed, the troops bailed out and flopped to the ground, and the lift hels departed. We flew in and landed to drop the DS off, and as soon as he opened the door the stench hit us - fresh coat of manure.
