If you want be an American soldier, the best thing is to contact the American embassy in Italy. They know what to do and perhaps are they able to test you there.
The other option is to find an American woman and marry her. However, a war is much calmer then a marrige.
the three rings of marrige, the first ring is the engagement ring, the second ring is the wedding ring, and the third rings which united them both is the suffering.
good luck
