How many frequency bands does the military use?

The military typically uses several frequency bands for various communication, radar, and navigation purposes. These bands can be broadly categorized into low frequency (LF), high frequency (HF), very high frequency (VHF), ultra high frequency (UHF), super high frequency (SHF), and extremely high frequency (EHF). Each band serves different operational needs, with some dedicated to secure communications, while others are used for surveillance and targeting. The exact number of frequency bands may vary based on specific military applications and technology advancements.
