@jambo12; the January 6th, 2020 Capitol video footage released to the public clearly demonstrated that some of Trump's troopers were indeed very well-armed.
Some were caught trying to find and kill Mike Pence for refusing to declare Trump President still while others scoured the building for Nancy Pelosi with the intention of tearing her to shreds.
The last death count I heard following the failed coup d'état was between seven and ten people.
Your query as to how could they possibly have taken power on January 6th will probably lead to films being made about just that - taking control of the Capitol appears to have been uppermost in the thought processes of those at the forefront of 'The Insurrection'.
