AboutPeter Eriksson Expertise Im capable of answering many of your questions about modern Main Battle Tanks and their configuration/construction/sub-systems. I can also tell you a thing or two about MBT ammunition like the DU-projectiles and Hollow Charge munitions if you like.
Experience I work as a technical officer in the Swedish armoured corps. I work on a daily basis with modern systems like the Leopard 2 MBT and the CV9040 IFV. This is something I have done for almost 4 years now and on my sparetime I sometimes help to restore old armoured vehicles. In addition to that I have a website at www.mainbattletanks.net dedicated to swedish armoured vehicles.
Question it seems like the US's military is so advanced, no country could stand a chance in war. Is there any country that could put up a good fight? How many countries would it take to take on the US military?
Answer If you are under the age of 15 I can understand because this is a very childish question. Listen up more in school and your question will be answered in due time.
If you are over 15 I suggest you start reading some books, preferably in politics and history (the last 50 years would be a good start). You should also travel to other countries and enlighten yourself in the workings of modern day society.
After you´ve done that, in say 2 - 3 years, you are welcome back with your question if you still find the question valid.
