Here's the refined poem, I have taken your comments into account about using the word 'the' less. It isn't hugely diffrerent but it should be a little better.
The gouging heat ripping apart,
Their final memories treasured in their hearts,
Blinding light dicing the air,
Shouts and screams combine with the glare,
Almighty is the noise of exploding shells,
This is the soldiers living hell,
Impressive trees withering through,
The godlike maiming force grew,
Their hearts have sunk the realisation of despair,
Losing the chance to finish their prayer.
I wrote this poem after seeing a poster of the film Platoon, and just wrote a poem about it. I dont really make up plans for poems I just kind of write them, and if anyone thinks I should use a plan for any other poems I might do.
