Motorization
1900: Experimental: A few cars and trucks have been bought by your army to see what they can do; everything else follows from this. This tech is granted automatically once the nation has the following techs researched: 1900 Internal Combustion Engines and either 1895 Line Infantry or Light/Cavalry
