Update 2.5
The United States had began to think twice on their botched attempts in salvaging german tech. Instead, funds and efforts have been redirected in to aiding research and developement of their own advanced weapons and vehicles, eventually succeeding and pumping out new and advanced american troops that are now up to par with their german counterparts. in other news, with the Imperial Japanese Army under total German-control, the United States Marine Corps have continued to receive funding and manpower, allowing expansions out farther than the Pacific and in to the dry lands of Europe, aiding fellow Allied Forces with their fierce spirit de-corps and arsanel of support vehicles, aircraft and naval ships.

Message from the Devs
With the release of Update 2.5, which marks the completion of the first part to the "Specializations Update Series", We would like to thank you guys for your positive support and comments for all these months! At first this mod started out as something stupid for me to explore a little more on the modding tools, despite the limitations on not being able to implement custom sounds and models, last thing we expected is this mod to receive quite the amount of attention (even if it may not be that much!). To positive feedback, helpful hands, videos-covered and even people willing to donate (We will be releasing donation links soon, for those who are feeling really generous!), the Devs and contributors to TAP thanks you all! We hope you continue enjoying this modpack, and we will do our best to continue improving and developing the experience!
