Range of engagements, and how?

[Metroyeti]

My flats a bit crap for defence. If someone or a group tried to break in I would stand at my living room door, got a corridor to my front door and fire my bow, pistol crossbow and my catapult, if they breach my front door im shutting my living room door and blocking it with a sofa, when they break through they will deal with me, my sheild and axe or machete.
