as mentioned use "what if" ideas. like did the attacker shove you down to the ground and you have to draw and shoot from your back? or are you planning on using a flashlight with one hand? try alternating hands. and different positions. on back. from chair.
I have been a silent witness
to all of America's finest hours.
But my finest hour comes
when I am torn into strips and used as bandages
for my wounded comrades on the battlefield,
When I fly at half-mast to honor my soldiers,
Or when I lie in the trembling arms
of a grieving mother
at the graveside of her fallen son.
