(Shorter post than I usually do- I didn't really have much in the way of ideas, though I will write a long one as it all escalates to set up the shot with a transitional.)

Andrew looked over, moving up onto the roof as they came out of the main factory itself. moving through a ladder that was covered by a hatch for roof access. Scanning the area, he switched off the rifle's light, letting Nolan ahead as they now had to head up the ladder, which went mid-way up the cooling tower on this roof. Andrew kept his Mk18 high, keeping an eye out for any movers down below as he kept the weapon readied.
"Let me know when you're up." Andrew said, looking towards Nolan, as he then checked the area of sniping- aware that the sightline was excellent for what they were going to do. He'd come back down here anyway, but he wanted to co-ordinate range markings, as well as get a picture of what his partner's view would be like- before setting a rappel on the side of the building to use, before then setting a few mines. They had a long, long time to wait, but snipers did that, and would wait as long as it took for the targets to arrive.
"Another two and a half hours of waiting. Better to have more time than less." Andrew said, following Nolan upward on the ladder, clambering up as he exhaled hard into the cold morning of Dushanbe- just another poor Central Asian country, with little to no political and economic stability. This was a part of the world you didn't hear about much- and the post-Soviet republics in this part of the world weren't exactly spewing money everywhere neither.

Coming onto a tiny metal platform, Andrew squeezed past Nolan, sitting down and letting his legs hang over the edge. He pulled his Rangefinder out, bringing a card out too with a marker pen.
"Okay..road is uphill and then flat when it meets the industrial area by the factory, goes from NE to SW. Goes right past the factory, though you don't want to shoot almost straight down, so the best place to shoot is where the road and the far end of the factory go parallel, roughly 600m. The massive puddle slash pothole just before that is 502m, so you can count that as 500m for the shot. Keep that as a backup if you can't get a bead at 600." Andrew said, watching on through his rangefinder, and marking the card up, setting it in such a way that Nolan could use it to mark up his shots.
"Vehicle is a modified Chevy of some sort, but up-armored. Resistant to all small arms, except 12.7mm AP rounds, simular to what you have. Now through the window, that'll just sheer it, so make sure that the first shot neutralizes the driver. The second follow up is for our guy, expected in the back- you should have shallow enough an angle to shoot Fletcher, or Ahmed at the 600 marker, but if he comes to 500, the shot will be too elevated. You can clip only get the driver at that point- and I'll have to make sure he stops, both Ahmed and Konstantin. I'll hold position by the metal pipes on the roof in cover, and once you cause enough confusion, I'll rappel down after I have it set, and clean the rest. I'll try and get the documents and Konstantin secured, either unconscious or willing, or dead if he's a threat, or if he didn't join your bullet's tip." Andrew added, still observing, the complete darkness only being killed by the distant street-lighting and moonlight keeping a little illumination around, as well as the fact the sun would be up any second now.
"Once I get him, I'll try and drag him into the factory- remember where we parked the vehicle? We'll get out of here and head across town, we've got a Land Cruiser stashed there, better than this local piece of shit- we'll get out of here and head south, towards the badlands- and deal with our guy in terms of well, what we want to know. Or at least get clear of here" Andrew added, watching Nolan set his rifle in, as he looked on, before looking back.
"Alright- I'll get to work getting the SLAM mines down. I'll detonate the first vehicle in the convoy- you know the rest." Andrew added, getting up so he could throw himself onto the ladder, and head down. He quickly came downwards, moving fast across the rooftop as he moved to his rappel point- where he'd go down it quickly, and use it to come back up when the mines were down, by clambering up via the rope.
