Specific Joint Tri service campaign plan

"Hello everyone on" Model Shipwrights, "I only usually go into Kitmaker or armorama and i want to pose a question for you flying people it concerns a campaign i am trying to get started based out of Armorama, but it has good potential for you guys to participate as well and you would be very very welcome, basic details are below, and the proposed campaign is called "Golden Memories"

Edited copy below from my Main thread for concept plan and rules

Has there ever been a campaign for modellers with ex military service to make models of the vehicles they have served in ?? it would be across the board, land based, aircraft and sea going vessels. But you would of had to of served and spent real time on that piece of equipment.
I thought it would be a cool idea as it would bring together people with the same passion for models from so many countries, and so many different branches of those military forces.

Edited Section from original post;

Here are the Rules/Conditions:
1. Build any vehicle/ship/aircraft you, your relatives/ancestors or a close friend have crewed/served in with a small back story.
2. All scales.
3. All eras.
4. No previously started kits.
5. Dios welcome.
6. Aftermarket add-ons welcome.
7. Build blogs are encouraged, but build for this campaign only.
8. At least two in-progress pictures posted in the campaign thread.
9. At least two pictures of the completed model in the campaign gallery.

Proposed start date: 01 Feb 2020 – End Date 01 September 2020
End date may be extended if needs arise.
