One time pads are difficult to use in Military settings because rarely is communication going on between just two participants. With the number of units needing to communicate some foolproof means for not using overlapping sequences of the one time pads between different parties is essential. Otherwise, a technique known as multiple anagramming can be used to reveal the plaintext. Generating a secure paper and pencil one time pad is very easy on a computer and can be expected to be completely secure if used properly. Of course, distributing, coordinating, and updating the pads is a weakness of such a system. In the electronic era, messages can still be encrypted with digital one-time pads and this was the case years ago when the secure “hot-line” between the Soviet Leadership and the US president used such a system to communicate. (The hot line wasn’t a phone but a teletype.) This was a perfect use case, a single pair of end points resulting in an unbreakable use of the digital one time pad.
