Translation of tank in Spanish

I am trying to learn Spanish because Spanish is becoming more and more important in the USA because of immigrants. Especially here in Texas. I used to live in Nevada for many years. Boring place, gotta tell ya.
Basically, I am here to learn Italian and French... some other languages as well, different cultures and meeting nice people. So far, I have made some friendships with Vocabulix, but I am always looking for more.
Thank you for your message. I am learning Spanish only for private purposes. Many of our neighbors do not speak English. If I'll go on vacation, I'll probably choose Spain or Latin America.
