Army - Syria move to Smyrna
Army - Armena support move Syria to Smyrna.

Same with fleets. Support holds only work if the unit they are support holding isn't moving.

Welcome to the site!

In order to issue a support to a moving unit, the supporting unit needs to be adjacent to both the moving unit and the destination. In your example, Syria indeed borders Armenia and Smyrna. In this case, the orders would be as follows:

A Arm - Smy
A Syr s A Arm - Smy

If the defending player wanted to support hold Smyrna, they could issue the following orders:

A Smy hold
A Con s A Smy hold

In the WebDiplomacy interface, a unit which is able to offer support is automatically presented with that option in their moves. Given the numerous alliance combinations, a unit will be presented with the support option as long as it is in a position to support any other unit, fleet or army, regardless of ownership of the other units.

If you would like to learn more about how the support orders work, I would suggest downloading an adjudication program such as jDip or Realpolitik.

Wait. I thought the ability to support moves and holds was monetized. That's why I PM'd my Chase bank account number to abge..........Oh, boy.

Welcome to the site!

Also, note that the drop-down menus for entering a support move puts the destination first.

Oh, and welcome to the site. It's great to have new blood here. Take note that if you have a set of moves put in, but don't hit save, but send a message, you have to re-enter the orders.

Oh wow, you guys nailed everything I was confused about.

I really appreciate it.

Welcome. Also sometimes the community will hold a tribunal and tax your diplomacy points for use on public parks and street repair in the territories you damage. Try to tell your army to minimize collateral damage it's bad press for the site. CNN picks up everything on here. It's like Anderson cooper has nothing better to do. Every night at 930 eastern standard time he has a story about some noob over bombing Tunisia with an air fleet. It's sad.

Ok I'm fine with it. My armies spread socialist agenda.

Just to clarify one thing 2ndWhiteLine wrote, to support a unit that is moving you do NOT need to be adjacent to the unit, you only have to be adjacent to the destination. So a unit in Constantinople could support a unit moving from Syria to Smyrna even though Con does not border Syria. It only has to border Smyrna.

Thanks for clarifying that yale, I was focused on the Smyrna/Armenia/Syria border and not thinking of the actual rule.
