After picking a gun at the farmhouse, the Crowbar is the best choice, you will have the option to use it several times during the game and its a good tool for not attracting attention.
This i believe is historically inaccurate, instead of the British being the playable from the Triple Entente, it should be the French, as the French had a greater part in World War I than the British.
Well, i have kept on playing the game (even after winning) and my 10+ scientist are pretty useless, and i have ca 115 in population, more than 50% of them being soldiers... so thus, i suggest you train builders because if you for example want to create an apartment, it will take 6 days with three people not being builders and 3 days with people being builders.
