High Frequency, typically defined as frequencies between 3 MHz and 30 MHz, have worldwide communication capabilities. The commonly used ham HF bands are 3.5-4 MHz (75-80 meters) and 14-14.350 MHz (20 meters). The 14 MHz band lends itself to worldwide communication during the day, where the 3.5 MHz band is better at night. Hence why the military still uses HF for their worldwide communications.
Also, the best transmission mode to date is continuous wave morse code as it will get through most any noise present.
No problem! As you get into it, you will find other modes of digital HF communication (PSK31, JT65, FT8, etc.) are just as good for bad conditions, CW still prevails and its also the original mode of radio comms.
