I have a newbie question on Tutorial Lesson IV.
Could you help me to find what is ARM and how to select?
I'm trying over PDb & HUD3.
The tutorial tells how to select the Standard Anti-Radiation Missile (ARM), but I have no idea what missile is the ARM.
Could only select RIM-66B SM1MR Block VI or RGM-84D Harpoon ID, but there is no ARM in the name. Tried the search through domestic Wikipedia and found Penguin Mk 2 Mod 7 (AGM-119B) is a kind of ARM, but the similar name was not found in the Weapons Available list. The below screenshot is taken when I attacked the surface threat.

PS I'm struggling against the enemy contact described in Surface Threats & Air defense Against Missiles of the tutorial and my vessel is always sunk.[:(]
