There s a lot more explosive in an ERA box than in a typical incoming warhead and there is a serious fragmentation and blast damage risk to those standing or sitting nearby The US doesn t typically let people ride tanks because tanks attract fire and people fall off and get run over fairly often a serious hazard in training and a significant hazard in combat and the US has plenty of Humvees and M 2 IFVs Other countries tended to both want to reduce training injuries and keep people away from the ERA blocks and restricted tank riding at the same time You saw it a bit in Chechenyia with Russian tanks but they lost a fair number of infantry to the secondary ERA explosions and stopped doing it I support putting the article back for that reason
