I'm sorry, I'm too lazy to type out individual suggestions :(
Do you think any for these changes are acceptable/possible???
You and I are marching in a united formation,
We have the same aim in our work and in battle:
To build peace on earth forever,
To build a bright world of working people.
Chorus:
Give me your hand, distant comrade,
We stand side by side.
We have the same destiny,
Our fierce struggle,
That's why our union is invincible!
Give me your hand, distant comrade,
For our union is invincible.
To make sure peaceful days don't disappear in smoke,
We will not let anyone ignite a war.
We will stand on guard for peace,
Keeping our powder dry.
Chorus-
Lets sing a song of friendship, sing it louder!
Our power is in the friendship between us!
In concerted formation we'll march through the world,
We'll march on our straight course to battle!
Chorus-
Almost word-to-word translation.
