Another patrol for second platoon, Alpha company, and Rob Corkrum – all 6-foot-8 of him – is wedged in the back of a heavily armored MRAP, with a sticker price of more than $500,000, crawling along a supply road outside Fallujah. This is January and as days go it's prominent in the memory, but in fact the days all pretty much run together. Alpha company runs lead operations, looking for IEDs – improvised explosive devices. Or in regularspeak, roadside bombs. The missions are 12 to 16 hours long, though they will be shortened somewhat when the insane heat of an Iraq summer is turned up. Every week, the company heads back to Ramadi where the battalion – the 321st Engineers – is based, for rest and repairs.
