Watched Heat again last night. For some reason this time round I was struck by how much the tactics of the robbers in the bank heist scene resembled that of military ‘one foot on the ground’ type movement under fire. Until I read this at imdb:
Lt. Hanna is shown “checking chamber” on his handgun in at least one scene. This is a trademark of the character Nick Stone in a series of novels by Andy McNab, who was technical weapons training adviser on _Heat_ . Although not an uncommon thing to do with a handgun, it is rarely given such visual prominence in films. Also, the crew’s tactics in the bank robbery shootout are notably similar to the “response to enemy fire” tactics featured in the book and film of McNab’s Bravo Two Zero (1999) (TV).
Look for yourself:
