Agh so many questions! Part 1- Pathfinders

Ok.... what happens with the pathfinders at D-Day? I'm filming a movie with them tomorrow and I've researched, but I still have questions I can't find.
So here's a walk through of the scene with my questions as they come up.

The pathfinders are in the C-47, it's night time of course. I don't know how many there should be in the plane, but there will only be 4 (that's all the actors I'll have tomorrow, so I have no choice.) The Jumpmaster stands them up.

Question 1: Would they go through the normal drop procedure or is there something special the pathfinders did in the plane?

The jump and land in flooded field. The quickly link up without being noticed. They were hardly under fire during the drop, they still have surprise. They rally and quickly cover their objectives (even if it's not what they would do, it's informing the audience of what's going on).

Question 2: What specific targets did the pathfinders need to find? I know they had to set of flares and smoke canisters, but where exactly?

They stand up and rush towards their objective, evading as many enemies as they can. They get wherever they needed to, wherever the answer to question 2 is, and light off the smoke.

Question 3: What color was the smoke? Green?

Moments later, planes are heard in the distance, but the Germans are alerted and track down the source of the smoke. There's a brief fire fight as AA guns rip open the sky and the Pathfinders are able to slip away into the darkness.


That's the scene. I'm hoping you guys can help with my questions.

 

The pathfinder aircraft for the drop in Normandy were normally fitted with Rebecca units (This is a reciever. The antennas are on the side of the plane just below the cockpit windows and look like miniature German radar antennas). Partisans, SAS, or other special forces-like troops already on the ground had set out Eureka transmitters on the drop sites. Each lead aircraft was homing on its particular Eureka (at least in theory). Between Allied jamming, weather, flak, the equipment not working right or not working at all, and mistakes in navigation among other things the aircraft often don't drop in exactly the right spot.
In Normandy all of the para drops were done at night. Smoke will not help. There are no specific pathfinder troops in the US parachute units that land. Instead, each stick was supposed to land relatively closely togeather, form up, and then form up with nearby sticks. Once halfway organized the officers present would determine their actual location from landmarks and set the unit in motion towards its objectives.
In the Market-Garden operation the 82nd and 101st landing in daylight made almost textbook drops that actually looked like the above.

 

Thanks. I'll revise the scene a bit to make it more accurate, but I still need to at least have a scene for the pathfinders. I'll let you know how it goes.

 

By a scene with the pathfinders, I now mean a scene with the beacons rather than actual pathfinders.

 

The unit looks like this:

A slight clarification of the pathfinders' role - a number of paratroopers in the 82nd and 101st were selected and trained to be pathfinders, who would drop first ahead of the main airborne force and set up signal lights and operate the Eureka transmitters that they jumped with into Normandy. The lights and signals (received by the Rebecca sets) were supposed to guide the following planes to the correct drop and landing zones, but unfortunately clouds disrupted the formations leading to confusion and misdropped paratroopers.

 

Thanks guys. I'm going to take this into consideration tomorrow while filmed. Check out the group on here for screenshots.
