Take out both. They'll count for later on.
Sounds like you're having a problem Harbinger1 with the TDC. That yellow triangle shouldn't be a problem. Red yes. It's taken me a long time to finally learn how to set up for firing torpedos, and now I can sink em pretty regularly... Unless I goof up from being in a hurry and forget one important step. This isn't manual Targeting but it's close. You don't need to line up the numbers on the ship and torpedo paths to get a good shot.
Here's what I do for a target:
Click on Turn TDC ON.
Use your mouse to Lock, and again to Break Lock. You should now see the box to Turn TDC On. Never mind will be at the bottom and will shut off TDC. So be careful you don't shut it down.
Click Turn TDC On and Lock again. Now you'll see the Recognition Manual. Identify the ship and get the info you need. I get the ships draft to set my torpedo depth. Now Break Lock. Now look in the box and it will say Turn TDC OFF. Click on it to turn it off. Now all you have to do is line up where you want to hit the target. OFF is is a must. You want to see Turn TDC ON so your torpedo will go straight and true to the target. I usually use Shift/Space to fire off a torpedo. It's faster than using the mouse to click on Fire.
Works 99.9% of the time. Escorts can be a bugger as they'll speed up and/or slow down, turn, or even stop. Let them get close, within 700 meters or less, and fire a steam powered torp set to FAST. They can't do a thing but blow up.
Practice this in a Single Mission so you get the hang of it, then...... Sink em all.
Good luck.
