Roughly half of the content creators on social media platform TikTok are under the age of 28. It’s just one reason why the popularity of Army Colonel Khallid Shabazz, who has some 43,000 followers on the social media platform, is so surprising. Most TikTok users hadn’t even been born when Shabazz joined the military 28 years ago and are of a generation with few ties to military service -- some 71% of young Americans between 17 and 24 are thought to be ineligible to serve due to health or other issues, according to a recent report.
