The New Age it’s a submod that expands the number of units , that Isengard can have. I like to make this to all the factions but it’s too much work for one person. This is how it works.
This is what you see at the beginning
And the new technology is the shield crossbow unit,
This tech its available they will folow the baron and KK the one ring scirpt.
for example the shield crossbow tech will be available only when the one ring will be at Erebor, and they need time to reached, they will be rare. So they r special.
Here is a in game shot
I this way I have add this units. For many I need the permission , like the horse, here r some screen shots
Heavy Bersekers.
Orthanc Guard Cavalry
Uruk Warriors bow
Uruk-Hai Infantry Javelin
And the Uruk-Hai Naffatun or bomb it will be added.
The mumakil is have been removed no permission ,or beter ignore.
Why i dont know, 
All the versions r not the very best in their field , like the longbows the EDU.txt is
stat_pri 10, 2, arrow, 190, 35, missile, missile_mechanical, piercing, none, 0, 1
and not like the elfs
stat_pri 10, 2, elven_arrow, 190, 35, missile, missile_mechanical, piercing, none, 0, 1
If I get the permissions I will upload it.I think many r OSP and only the credits r ok.
