After Mike and Tanya got to America they stayed together for two years and fought together for the US when they conquored Mexico and a good portion of Latin America. After which they got married and Mike ended his time as a soldier and became an inventer, mostly weapons and military equipment. He did his work at Springfield Armory with Tanya as an assistant. At some point Mike wanted to have a meeting with a Sir Hiram Maxim, an American inventer living in Britain to talk about his gun he called a "machine gun" which Mike was interested in and some were saying it was the future of warfare. So yet again Mike boarded a blimp to Britain but this time with Tanya along. When they arrived they already could tell war visited Britain, there was burnt out buildings and bomb craters everywhere along with large groups of homeless people. Traffic was nonexistant in London because of the damage so the two had to walk everywhere which took alot of the day. The two then began there search for Sir Maxim.
