Ive only started my campain and havn't upgraded to a Type VIIC as yet (prob next patrol) - but while playing in "Single Mission" mode (the protect the Bismark one, can't remember exact name) I chose a Veteran Crew, 1942/43, and a Type VIIC (U-556) as per mentioned above (phew!) anywayz .... I know the different methods, hotkeys etc involved in getting your crew to man the AA Flak Guns, (F11, F, T, G) but for the life of me I cant get them to man the larger (is it a C/30 3.7cm Flak i think?) positioned lower down & between the other two smaller Flak guns (which they WILL man). The hotkey will take me to the view for it, but un-manned i can't use it. I think the conning tower in use is the VIIC/3 variant. I know u can't man them in rough seas, but even when its calm enough that the smaller Flaks get manned, this one still remains ghosted in the "crew on deck - Flak ..." menu & un-mannable?

I've RTFM and i just cant suss this one out ?? is it an "upgrade" that i need which i don't yet have? any help would be very much appreciated, TIA. btw - i've been playing Silenthunter since the Orig version, and have them all, what a dream come true to see it progress to this its present incarnation - magic!
