Cross-posted from FTAlphaville:
Morale-boosting military messaging intended to recruit and galvanise troops, while prompting patriotic goodwill with the public, is nothing new. Such techniques have been in play since war itself was invented.
In the 20th century, the military took advantage of the media of its day: broadcast radio, video and celluloid film. In 2020, it would clearly be negligent for it not to take advantage of the craze for musically backdropped micro-clippable content shareable on social media.
