There are very few writers who can make battle sequences worth reading. It is difficult to make battle sequences both vivid and clear. I think John Ringo, W.E.B. Griffin and J. Curtis are as good as it gets.
The challenge is compounded by the fact that the the vast majority of the people on the battle field have a very fragmented understanding of what is going on. Not only does the fighter-on-the-field have a very narrow window into events but it is distorted by the fog of war.
One technique writers use is to place the battle in a barren, easy to describe landscape. Consider how Griffin started his book The Lieutenants: The opening scene is of a sparsely vegetated, undulating dessert where the vertical relief was sufficient to hide a German Panzer Tank.
As a writer, I chose to have Chernovsky's forces criss-cross the landscape umpteen times during training. That way you knew that they had intimate knowledge of every square foot of that landscape. They knew each bush and saddle and boulder, swamp and bump. As readers, we expect rational actors to take maximum advantage of the field-of-play. Quinn would not bury himself in a hole filled with cattails. Rather he would hobble to the best vantage point, in this case a rock pile that gave him elevation for improved battle field visibility and a solid barrier should he need a steady rest for firing or to shield against incoming fire.

There is only one play in football. The only thing that varies are the details. Present "evidence" that you are going to move the ball in a certain way and then move the ball in a different direction or different mode, preferably one which catches the defense in a sub-optimal configuration.
Battles are same-same. Present evidence to the target to get them to focus in the wrong place: A string of fire-crackers going off, a puff of smoke, a pretty girl or an ice cream truck, a flash-bang in the middle of the room. Then pour the fire to them from a direction they are ill-prepared to defend against. Bonus points if the fire is "stealthy" and the defenders are not capable of deducing the nature of.
I know my limitations as a writer and make some assumptions about you, as readers. Rather than have your eyes roll back in your head as I bury you in excruciating detail, I prefer to skip lightly across the tops of the waves and let your imagination fill in the details.
