After Supreme Leader Snoke gets Mauled by Kylo, his Praetorian Guard leap into action to avenge him. Rey and Kylo are heavily outnumbered and it's a tough fight for them since the Guard have weapons capable of withstanding light sabres.
My question is: why don't the pair use the Force (beyond innate usage in terms of improved reflexes etc) to give them an advantage? We later see Kylo Ren use Force-choke on Hux, so at the very least we know he has that ability in his arsenal. He also throws Rey with the Force in TFA. Rey is also later able to lift an impressive number of rocks simultaneously, so presumably she could muster a Force-lift/push to throw the Guard around. It's worth noting they both attempt a Force-pull moments later in their own duel.
I'm only familiar with the movies (although I've watched a little Clone Wars and SW Rebels animated series, but not much and certainly not enough to answer this). Is there any canon reason why people capable of using the Force would not do so, does it require special training, or maybe there's a particular reason they couldn't use it against the Guard (are the Praetorian Guard, or the Royal Guard they were based on, protected from Force usage in some way)?
