I get easily confused when playing both SH3 and SH5:
In SH3 (WAC, etc.), german text:
From left to right:
Kontakte melden (= wrong translation, should read Statusbericht senden = Send Status Report; same as in the radio message screen)
Fühlungsmeldung senden (= Send Contact Report; same as in the radio message screen)
Feindliche Kontakte melden (??)
In SH5 TWoS, english text:
The 3 ones from left to right:
Report received contacts (??)
Send Contact Report
Send Status Report
No idea what the marked ?? actually do, reporting any sort of contact (excluding convoys for which you use Send Contact Report) ?
