Hi Cat
Yea so you can only have 1 Elite in a TTy. Elites can only be placed in their Capital, so triplea is able to enforce this for the Capital TTy only. Other TTys are Player Enforced.
So you need to remember to move the previous Elite out of the Capital TTy or it won't allow you to place.
Also, Paratroopers do not place in the 1st place phase. They place same as normal Inf with the exception that they can only be placed in their Capital.
And generally you will want to demo Infrastructure during 2nd place so you can use it during your turn if you want.
Edit
Yea if you buy the demo harbor unit, it will kill the Harbor when you place it. No biggie as you used edit to create the same result. It looks kinda cool to see it "en fuego" though π
A note about Commandos and Marines. It is best to pair them with Arty on a 1:1 basis so they can get boosted to 3 on attack. The way triplea has to do it, is make the standard Marine/Commando, the one you purchase, Attack 2 D2. The Arty gives plus 1 to make A3.
However, if the Marine/Commando doesn't have Arty support, it will attack at 2 which is incorrect. It should attack at 1 same as a normal Infantry.
In that case, you need to use edit to swap it with a "MarineA1" so it will only attack at 1.

It would be so much easier if they just attacked at 2 regardless but those are the Captain's rules and he isn't interested in adjusting them π
That's why Armored Inf is a better buy for USA but they are limited, so the Marine still has a place, especially early when US economy is still making Fords π

You should also get savvy with Rail movement. For example instead of moving the 2 S Africa Inf 1 space, in NCM you can move to Egypt if you want. As long as you have a continous string of connected TTys at the Start of your turn.
Click on the Rail Unit and then click on the Inf and move him where you want. Some Country's have different restrictions than others.
