Metallica - Green Hell (btab), аккорды

Though most of the songs on Garage Days Re-revisited are
 tuned down a step (at least on 
E
), this one isn`t.
 
 
 
 One of the riffs is just doing a lot of 3`s on the 
E
 
 string,like below. The timing is something like 
 16th notes.
 
 G|--------------------------------------------------------|
 D|--------------------------------------------------------|
 A|--------------------------------------------------------|
 E|-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3------------|
 
 
 Another riff in there is this, the main one....
 
 G|----------------------------|
 D|------------------------1---|
 A|----------------------1---3-|
 E|-3-3-3-3-3-3-3-3----3-------|
 
 
 
 The last riff is this, used in the chorus, 
 "green hell, green hell" part.
 
 G|---------------------------------|
 D|---------------------------------|
 A|---------------------------------|
 E|-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-|
 
 
 G|---------------------------------|
 D|---------------------------------|
 A|---------------------------------|
 E|-0-0-0-0-0-0-0-0-0-0-0-0-0-0-0-0-|
 
 
 
 After one of the chorus`s (either the 1st or 2nd time,
 I`m not sure), there is a little fill that goes 
 something like the little riff below.
 
 G|--------------------|
 D|------7-------------|
 A|-5-7----7-5--------|
 E|--------------7-6-5-|
