Why is your whole story filled with more holes than Swiss Cheese? How could they recover the one injured guy but not the bodies of the two KIA? And if they weren't "safe" at the time, they'd duck for cover, I get that, makes absolute sense, however they wouldn't magically end up at their post! They would be in that general vicinity until the fire died down enough to allow them for free movement. They would ask nearby posts, direct fire and in the meanwhile, a rescue party would be dispatched to extricate the injured/dead. Your story runs counter to basic SOPs and broad logic.
Regurgitating media hype is one thing, but it appears you have no idea about rules of engagement and military protocols in general and are specifically ill-informed about the nature and reality of skirmishes along the LOC.
