Martial training is the only thing I've experienced that reminds me of my time in the military.
I have been a veteran now 35 years, and yes I remember faces and acts of courage. Heads down, covering each others back, and making sure no one was left behind. Sorta bonds you in a way that only those who have been there would understand.
IMHO, it is the training that bonds many of us whether we will ever actually meet or not. I remember those who taught me and those who shared the training.
Everyone is still with me, every time I train.
Thank you for reading and responding.
