"You can always take one with you" is the proposed campaign in the event Sealion (German amphibious invasion of Great Britain) was attempted successfully. Having actually seen Overlord (the exact opposite scenario, "D Day") we know Sealion could not have worked, although of course in 1940 the British couldn't know that and were right to worry about it.

Since Hitler's general staff believed Sealion wouldn't work it was never attempted and so although "You can always take one with you" was considered it was never actually used.

There were guerrilla units established who had more targeted training (ie. To assassinate collaborators in any puppet government) but that wasn't necessarily a suicide mission and it wasn't general, the "you can always take one with you" messaging would have addressed the general population.
