Mandatory Confessions

After the recent business with the British Sailors, it seemed to me that a good way to undercut this sort of strategy and help protect your troops in the field would be to simply have a standing, and very public, order that captured troops must agree to sign any confessions and make any statements that their captors require.

By making it official, it stops being about whether or not your soldiers are tough enough to resist, or even whether they were coerced into finally revealing the secret truth, and instead just about them following standard policy.

When a captured soldier is put on TV, the Prime Minister or President can come out and say that they're doing their job -- and that if they'd been ordered to admit to killing Kennedy and making blood sacrifices to Satan, they'd say that too -- because the purpose of the general directive is to get the valuable government property of these soldiers back home.
