German Sniper Badge (1944-45): These were introduced towards the end of the WWII to distinguish the German snipers. Since these badges were introduced so late in the conflict, they are quite rare.
Electronic Attack Squadron - "Zappers": VAQ-130 is the oldest electronic warfare squadron in the United States.
The Special Boat Service (SBS) is the special task force of the British Royal Navy. They are similar to the American Navy SEALs. This is an older version of their badge. Their current one is much more austere.
