This might take a little to get your head around 
The idea is to also extend this to Infantry weapons aswell. Part 1: Vehicles, Part 2: Infantry Weapons
Currently in Enlisted, there are many versions of the same tank/plane, with very minor differences/upgrades over their predecessor. In the interests of still having all these historic and interesting models, but also unclogging the research tree and making room for more models, @gastanofrizzi has suggested an interesting alternative.
This is the vision of @gastanofrizzi. Presentation assistance by @Myrm1don .
Instead of Unlocking the same vehicle/plane multiple times in the research tree (potentially accross different squads/crews), instead only the base Version of each vehicle, and Squads will be in the Research tree. Squads will now come with a “Crew Certification” which will determine what vehicles they can operate. All Vehicles will now have a place in the Shop where you can buy them at will, much like weapons . (Providing you have unlocked them)
IMPORTANT NOTE ON GRIND: This doesnt mean that it removes the grind however, its just moving the grind from the Research Tree, and allocating it to leveling up a squad instead (which will have a much higher max level to accomodate all the points needed to unlock every Vehicle). It also allows you a bit more freedom to research what you want first, Providing you have unlocked the Base model in the Tech tree)
To prevent cycling Powerful Heavy tanks or Heavy CAS as you unlock them (for example 3x Tiger 2/IS 2 or 3x Ju188s/P-47s) the following Certificates are available to each squad Type (Including Legacy Squads). A certificate is just a passive attribute assigned to squads that determines what vehicles are available to them:
Certificates By Squad type:
Tanker Squads
Tanker I Squad - Light tanks, Medium Tanks, Tank Destroyers
Tanker II Squad - Light Tanks, Medium Tanks, Tank Destroyers
Tanker III Squad - Light tanks, Medium Tanks, Tank Destroyers, Heavy Tanks
Fighter Pilot Squads
Fighter I, II and III Squad - All FIghter Aircraft
Attacker Pilot Squads
Attacker I Squad - Light CAS, Medium CAS
Attacker II Squad - Light CAS, Medium CAS
Attacker III Squad - Light CAS, Medium CAS, Heavy CAS
*Note this does not mean you cannot put “Tanker 3 Soldiers” in a Tanker 1 “Squad”, It just prevents puting another Tiger 2H in a tanker 1 and 2 squad.
So for example, Instead of having to unlock and buy ALL 5 of the Panzer III models in the research tree , you would only have to unlock and buy the base model (Panzer III B). All crews with Medium tank Certification can now equip and use the Panzer IIIB.
Similarily, Instead of having to unlock 8 BF 109s, You would only have to unlock the base version (Which is currently 109 E7/U2)
Should you wish to unlock the various other models and upgrades, you must play and level up the Squad itself (Any squad with the right Certification). Models will now be unlocked by spending squad points in the corresponding tree.
You can choose which model to put your squad point in. The vehicle will unlock for purchase after the *first point spent on it. (Up for change)
(NOTE: You must have a squad with the appropriate certification, and the base model unlocked in the Research Tree)
For example:
Once you have some unlocks, It will all be managed via your squad customisation
Via the Customisation menu, You can swap between the variants of the “Base Model” tank you have equipped. Obviously , this can change the BR, dependant on which Model you use.
This also maintains your crew, your Camo, decals and decorators inventory all on one squad!!!
Dynamic Appearance for different Campagins is also selected here. (THIS ONLY APPLIES FOR VEHICLE CAMOFLAGE/DECALS/DECORATORS, NOT CHANGING MODEL. It would be very cool to dynamically change model aswell, but that might make it super difficult for the Devs 
)
Imagine, as a Crew gets more Experience, they earn the right to the nations more powerful and upgraded models. This will also tie into the future possibility of Veteran or ACE crews, as you will be able to maintain the same crew.
What is the point, and advantages of this system?
The Main purpose is to Removing clutter and streamlining Vehicle Progression. It allows the player to advance in the Area they would like, and allows the player to avoid having to buy many versions of the same vehicles they do not want.
Going forward, It also makes it easy to keep adding many more Models for already existing vehicles to the game, without affecting players progression in the research tree.
Tanks
- USA relocates around 10 vehicles variants from the Research Tree
- Germany relocates around 13 vehicle variants from the Research Tree
- Soviets relocates around 8 Vehicle variants from the Research Tree
Planes
- USA relocates around 5 variants.
- Germany relocates around 13 variants
- Soviets relocates around 8 variants
Currently you have to buy everything before you can advance. This systems allows you to bypass “some” that are of the same model lines that perhaps you have no interest in, saving that precious silver.
Other Advantages:
- Many models can be added of all tanks/planes without interfering with your Tech Tree Progression
- Maintaining the XP and veterancy of a Squad, crew
- Player has more say in where their silver is invested
- All Vehilce Camoflages will be tied to the squad and not the individual vehicle. (can be used by any vehicle the squad uses). This gives the player more freedom with his customisations.
(eventually it would be nice to be able to swap between these models “in game” based on situation)
It can be a bit overwhelming to understand what is happening here, But I think it is an interesting Idea with some cool features and deserved to be thrown out there. Any questions, suggestions or further improvements, I am sure @gastanofrizzi will be eager to indulge!
