If the transport were able to move exactly the quantity of units of the
given type remaining in the transfer without moving the whole order, the
transfer order would be left with instructions to transfer zero of that
unit. That's an invariant violation, and was resulting in _later_
transfers attempting to create a convoy with zero units, which pydcs
rightly rejects.
For example: if 2 Abrams and 2 Paladins are ordered to transfer from a
disconnected FOB to a distant location that is connected by road, and
only two cargo slots are available, that transfer could be split into:
```
{
Abrams: 2
}
```
and
```
{
Abrams: 0,
Paladin: 2
}
```
Depending on the route, those airlifted units might end up still needing
road transit (we prefer short airlifts rather than direct routes because
it gives the player more opportunities to intercept enemy convoys). The
current turn would airlift the Abrams-only group and the Paladin group
would wait. On the next turn the Abrams would travel by road and the
Paladins would be airlifted. On the _third_ turn, the Paladins (and zero
Abrams) would generate an invalid convoy.

About DCS Liberation
DCS Liberation is a DCS World turn based single-player or co-op dynamic campaign. It is an external program that generates full and complex DCS missions and manage a persistent combat environment.
Note that DCS Liberation does not support the stable release of DCS. We can only guarantee compatibility with either the open beta or the stable release, and more people play the open beta. DCS stable might work sometimes, but it's untested, and we will be unable to fix any bugs unique to stable DCS.

Roadmap
Our plans for future releases can be found on our Projects page. Each planned release has a Project, and the page for that project has columns for to do, in progress, and done. Items in the Done column are in the preview build for that release. Items in the To do column are planned to be added to that release.

Special Thanks
First, a big thanks to shdwp, for starting the original DCS Liberation project.
Then, DCS Liberation uses pydcs for mission generation, and nothing would be possible without this. It also uses the popular Mist lua framework for mission scripting.
Excellent lua scripts DCS Liberation uses as plugins:
- For the JTAC feature, DCS Liberation embeds Ciribob's JTAC Autolase script.
- Walder's Skynet-IADS is used for Integrated Air Defense System.
Please also show some support to these projects !
