The meaning of poem 'ANZACS'

Hi, I'm Jessica, I'm just immigrant from another country.

I'm very interted in the poems

but My English isn't good enough to understand actual meaning of the poems.

So I wonder if someone can help me

this poem is very interesting poem about Australia which I didn't quite understand..

ANZACS

Edgar Wallace

The children unborn shall acclaim

The standard the Anzacs unfurled,

When they made Australasia’s fame

The wonder and pride of the world.

Some of you got a V.C.,

Some ‘the Gallipoli trot’,

Some had a grave by the sea,

And all of you got it damned hot,

And I see you go limping through town

In the faded old hospital blue,

And driving abroad – lying down,

And Lord! But I wish I were you!.....................................<<Why??

I envy you beggars I meet,

From the dirty old hats on your head

To the rusty old boots on your feet –

I envy you living or dead.

A knighthood is fine in its way,

A peerage gives splendour and fame,

But I’d rather have tacked any day

That word to the end of my name.

I’d count it the greatest reward

That ever a man could attain;

I’d sooner be ‘Anzac’ than ‘lord’,

I’d sooner be ‘Anzac’ than ‘thane’.

Here’s a bar to the medal you’ll wear,..........................<<How?? did he get the medal??

There’s a word that ill glitter and glow,

And an honour a king cannot share

When you’re back in the cities you know.

The children unborn shall acclaim

The standard the Anzacs unfurled,

When they made Australasia’s fame

The wonder and pride of the world.

I just bolded the the sentences which I don't understand

Also, can you just tell me a short and simple meaning/story about what is going on in this poem and what is a poet trying to describe/tell us.

PLEASE....plz
