I generally don't think of my family as being very militaristic (many of us are among the anti-war, pacifist types), but we have our fair share of veterans in the lot. My grandfather, William Angus Koehnline was in the Naval Reserve in WWII, as seen here:

His father, I.J. Koehnline, was a member of the 324th Field Artillery in the US Army in WWI. We're lucky enough to have a large collection of his letters home during the war, describing his experiences & travels through Germany & France. Here he is in uniform:

I.J.'s brother also went into the army for WWI, & came back with very severe PTSD, as I have written about before.
I wrote about my great-grandfather J. Lawrence "Lorry" Jurgensen for last week's photo of the week; he was another Navy man in WWII.
A handful of other relatives were veterans, but the one I'll end with was a great-great-granduncle, Joseph Russell Neer Monroe, who enlisted in the Eighth Iowa Cavalry, Company F in the Civil War. His brother, my gggf, wrote quite a bit about his life & service. From his account I post the following:
"In October of 1863, they marched from Louisville, Kentucky to Nashville, Tennessee.
On the Northwestern railroad, ninety miles out from Nashville, they went into winter quarters, but not to rest. All that winter they were kept busy scouting, and fighting guerrillas They took many prisoners during the winter and escorted them to the prison at Nashville.
When spring opened up, they fell in with General Sherman’s army and took up their march south. They struck the rebels in force at Dalton, Georgia and from there on, it was almost continuous skirmishing and fighting the whole of the way from there on to Atlanta, that being the place where they made their last great effort to annihilate Sherman’s army before he could make his famous march to the sea.
Joe was in the battles of White Pine Church, Buzzard’s Roost, Lost Mountain, Ringold, Franklin, and two other battles while on that raid. He was also in the battle of Cassville, Georgia, and at that place had a part in one of the grandest and most daring cavalry charges that were made during the civil war."
I would post more of my gggf's account, but I feel I would be taking up way too much space (already taking up a lot). When I create Joe's profile, which I have yet to do, I'll be sure to include the whole of J.A.'s writings, which describes in great detail Joe's experiences, later being captured & imprisoned by the Confederates. The rest of his life was quite interesting as well.
