This is an interesting idea, but I think some things could be strengthened: I would suggest punctuation as that would make the poem easier to read and would make it scan better. I would also try to find a better example for 'touch' as touching tears doesn't seem as possible, or immediate, as any of the other examples. Lastly, I would make the second to last line 'and as these soldiers soon /find/ out' because the start of the poem is in present tense, not past. That said, it's an interesting idea that could easily be worked upon and, if you want, probably expanded into a longer or stricter poem; I'd be interested to see what could be done with it in formal verse as well.

Good poem. I like how you entwine it with the different senses, it makes it more real.
