I just wanted to write sumthin'

What do you think of the voice?

I've been really close to things blowing up three times.  By really close, I mean potentially lethal shrapnel hit stuff behind me.  I still have a piece that embedded itself in a board I was standing next to.
The first time it was a mortar. Boom! The low frequencies seem to push your entire body inward, and your breath is forced out of you.  That time, my eyes shut and my entire body contracted as I collapsed to the ground. For the first time I heard the short burst of static caused by shrapnel and falling debris hitting the ground and buildings around me.  I yelled "Incoming!", then, still shaken, got up and ran to a bunker with my head held low.  The second time it was a rocket. I saw this one coming and watched the thing blow.  Fortunately the rocket went over my head, so most of the blast was directed away from me.  I only saw it because it was so fast!  The moment I heard the buzz and saw it coming at me, I moved to run, but it happened so fast that I had barely begun my turn when it blew.  I continued the movement and ran for several meters before slowing to a jog towards a bunker.  The third time was close.  Another mortar. The short whisper then Boom! The low frequencies are what you really miss on TV.  It was familiar now.  The pressure, the noise, it passed over me in an instant.  I took a deep breath and looked at the shrapnel in the board next to me.  I dug it out with my knife.
One night I was in a convoy, and our route took us under the arc of an artillery barrage.  It was foggy so the muzzle flashes from the guns and the explosions lit everything as the rounds whistled through the air.  I thought about being under that, and about the guys in WW1 and WW2.  The best the people who were shooting at me could manage was a couple of mortars and rockets a couple of times a week.  Old surplus ordinance, no less.  
You know, it's "illegal" to take shrapnel, and most other real war souvenirs home now.  I did anyway.

cool story bro

I see little to no voice here. Most of it is describing what happened with no hints as to how the speaker feels about it, save for the allusion to WW1 and WW2 in the last bit. Work on the thoughts going through your mind instead of what was going on around you. Both are important, but this passage just feels dry.

Thanks.  I may not have meant "voice".  What I meant was how does the language read and flow.  Is it clear?  Does it sound natural?  Isn't that "voice"?

It's moderately clear. Is the story about being in a war zone? It spends a lot of time on the first explosion, which was good. Maybe you could elaborate on the situation, like where the rocket was coming from or where these bunkers were, or where the mortars landed.

It feels very shaky and ungathered.

>I only saw it because it was so fast!

This makes no sense. You are less likely to see fast things. Maybe you mean because it was so loud?

It made no sense to you, because apparently my next sentence wasn't clear.  I saw the rocket and turned to run but it happened so quickly that it had covered a couple of hundred meters and impacted before I was even able to avert my eyes.  Thanks for the input.  I'll tell you what; I can't but laugh now when I see people jump out of the way of rockets in movies.

Why do you change POV and tense multiple times over this passage? There doesn't seem to be any reason to...

Well, looks like you really did write... something! Just like you wanted. Good job!
