It's certainly not one of those stories designed to ram home the point that soldiers do what they do because of their unfaltering love for the man fighting beside them.
I was made to recall one of my favourite shows of the 70s, Danger UXB with Anthony Andrews. The unexploded bomb scenario certainly makes for remarkably tense viewing, such that when you come to watch one of these second time round, the emotional experience is significantly different. (I don't remember such edge-of-seat cinematic experience since United 93, though of course in Greengrass's movie you knew exactly who was going to get it.)
My admiration for Bigelow's film faltered only during the extended spaghetti western-style scene around the mid-point, in which Ralph Fiennes and co put in an appearance as an unlikely group of British contractors. But overall, a landmark war film with fine performances from the central trio.
