When I was a LEO I saw over time that there were some officers who got into more physical altercations than others. Some officers had a resisting arrest charge with nearly every DUI or domestic dispute call.
I started studying this and learned that much of it had do to with the officers (demeanor/actions) not the perp. A few of the officers were cocky, loved the 'unfair' fight and would egg the perp on until they did something stupid. Some officers carried themselves poorly and were seen as more of an easy target. Not good for a LEO. I preferred to keep things as short as possible. Once assessment was made, I tried to get the cuffs on before the perp really had a change to process what was going on.
That's my experience too, less so with who I worked with but absolutely spot on for the military police, I found them a total nightmare fot his reason, most soldiers will go quietly for civvie and MOD police but hated the 'monkeys' as the RMPs are called.
