Is Barbell Strength Sufficient?

I assume safety and injury prevention in training is paramount. Read the post employment programme. In your experience, does an operator particularly need barbell strength, or is it body weight, kettlebell work sufficient? Am, i think they need barbell work because you also need to be flexible and mobile and fast and have a ton of endurance. Cardio is fine. But if you have to pick your buddy up and carry him ten kilometers, like my friend did - that comes from here. And i mean, when i'm talking about here, i'm taking by real, true courage. That's a little different for this group. I do not know how you don't train that.
