TDC Dials when using Attack Periscope.
 

Iv'e just watched Neal's film on Game Shadow showing attack proceedures (convoy).
I noticed on the "Range, AOB and Speed" dial there are five positions to work with. The three I mentioned here and "Lock plus a.n. other I cannot see too clearly", making five (5) in all. Am I missing something as I only have the three on this dial..."Range, AOB and Speed". Is this Mr Bush having a go (in cahoots with Ubisoft) at the EU DVD's their handing out? Tis a puzzlement!
Would some one shine a light my way and help out please.....Thanks in advance....Dusty.

P.S. A huge THANK YOU for all you guys and dolls who are putting so much work into SH4. Its a cracking game!!!!
