I served with Mark in Iraq with the 101st C-RAM mission. An amazing man, a family man, a true warrior. What I remember most is that he loved to make you laugh. He had jokes for days and was easy to talk with. He cared about his troops, those people in his life and it showed. He also loved to talk about his family. My heart goes out to you all who knew him, we lost a good one. For those that didn't have the opportunity or didn't take advantage of knowing him, you missed out. "God will give us only as much as we can handle." Rocket Buddies for life, Godspeed Sir. Mr. Mike

My condolences to all the Glenn family as well as Mark's many friends. While I only had the privilege to meet Mark once it was an honor. A solid guy as they come and an"giver" in life. Thank you for your service. #RIP

To Uncle Lester, Aunt Judy, Kerry, Julie, Michele, Jessica, Erin, Mia and Julia: So sad to hear of cousin Mark's passing! So proud of his and Uncle Lester's military careers. My mother, Joyce, always kept me up to date with everything 'Glenn' in the US. As long as I can remember, she told me stories about growing up with Reginald, Roger, Doris and Lester. Reading what others have written about Mark tells me that he too is a strong person with a great sense of family and sense of humour. Please know your Canadian family is thinking of you. You will always have fond memories of Mark. He will always be with you ❤️. Love and respect, Cousin Glenn

To the Glenn family, I'm so terribly sorry for your loss. Mark Glenn was hands down one of the best battalion commanders I had the pleasure of serving with. We first met 20 years ago when we deployed to Iraq together, and the entire time I knew him, he was a no-nonsense, but kind hearted and fun loving man. In life, you sometimes have to make unpopular or otherwise tough decisions that can upset others. Mark had a knack for tackling these decisions in such a way that there was no ill will or resentment hanging in the air afterwards from either person. He was a man who preferred funny stories and jokes to doom and gloom and my military career is better from having known him for almost the entirety of it. Rest easy sir, I'll see you on Fiddler's Green! -CW2 Armand Hunter

We did not know Mark but Mia is on our daughter, Maddy's CYO basketball team. We are so sorry for your loss and will keep the Glenn family in our prayers. - The Durrell Family

Mark and I had known each other for some time in the Artillery community but we did not get to serve together directly until about 2006-2007 at the Yankee Brigade HQ. I am grateful I had the opportunity. We exchanged a lot of war stories and joked that going to drill was therapy. He told a story one morning about a news report of a shark in Lynn harbor that still makes me laugh. You will be missed, Mark! Vincere et Vivere

My deepest condolences to the Glenn family. Words cannot overstate the loss you must be feeling. Mark was the consummate warrior and professional. He superbly commanded 1-101 FA during the most recent deployment and earned the 86th IBCT nickname of the "Brigade Ace" (many times over) for the number of drones and incoming rockets his Soldiers shot down. His unit's performance during this non-standard mission was exceptional and he set the standard for others through his personal attention and leadership. Mark fervently cared for his Soldiers, and I am honored to say that I had the pleasure of serving with him.

I never got to know Mark, but what an amazing life of service. I'm so fortunate to have Julia in my class and it's easy to see where she gets her tenacity, independence, bravery, and imagination. Wishing you a measure of comfort through this difficult time and always. -Tom C.

Joyce ,, Maura and the Glenn family I am so sorry for you loss Mark will be watching over all of you especially his beautiful daughters and wife.

We were lucky enough to have spent some time getting to know Mark at Johanson family reunions in TN and UT. Sadly, way too little time, but enough to recognize a man that was a loving husband and father. Those who have served, and the loved ones of those who served, REALLY understand that freedom is not at all free. Colonel Mark C Glenn is a true American hero. God rest his soul and watch over his family. From Dave and Patty Johanson

I first met COL Glenn 25 years ago when I came to the MA Guard from active duty. It's been over 20 years since I served with him directly but, I've never forgotten him or who he was as a leader. He would light up a room and could make you smile in the worst conditions. I pray that God will ease his family's sorrows and provide comfort. Until we meet again Sir. -MAJ(ret.) Jack Parisi

Legally, he was my son in law. In reality he was my son. I had so many laughs with him, hours around the campfire, sharing music, a bit of Single Malt or a beer, and serious discussions about life. I'm crying as I write this and can't believe he's gone. Jess hit a home run when she found you. Erin, Mia and Julia were blessed to call you dad. God's peace be with you, Mark, till we meet again.

Uncle Lester, Aunt Judy and families, I was shocked and very saddened to learn of the passing of cousin Mark when my mother Joyce Glenn Ward told me. We would always look forward to visits from our US cousins when we were younger. I got to see the girls more as we got older as Mark was busy with the reserves. We were so proud of his academic accomplishments and followed his military career with pride. Mark was a fine man and will be missed by all wio knew him. Thinking of you all at this most difficult time. You are certainly in our thoughts and prayers. Hold tight to all of your precious memories of Mark. Sending much love, Cousin Brenda

I'm so sad to see this. He was my Battery Commander when I was in. A soldiers soldier. God Bless.

I am shocked and saddened hearing the news of Mark's passing. I have not seen him in a few years as many retired soldiers will see people at the Hanscom complex. I think I saw him at the commissary in exchanged a few kind words. I did serve with Mark at the 51st true command where I was the logistics officer and Mark was the training officer and we would sit in his office by the back door and shoot the breeze for what felt like ours with our past experiences in our views on whatever political thing was happening that day. Reading his obituary made me feel that he was able to achieve what he wanted on this earth, just hearing he leaves such a wonderful family to carry on his memory. It seems like yesterday we lost Mike Greene and now another true warrior. Mark until we see each other again. Rest in peace. -your friend, Mike Currie

To Uncle Lester, Aunt Judy and family: I am deeply sorry for the loss of your dear Mark. As a cousin, I am very proud of his military accomplishments and of the fine person he was. My late mother, Doris (Glenn) Bishop, always spoke highly of your family and of Mark. May your precious memories bring you peace and comfort with time. With love, Jeanette (Bishop) Baker

Aunt Joyce let us know of Mark's passing. This was saddening news. We think of you folks often, especially since Mom and Dad are both gone now (Earle and Doris). We send our deepest sympathies to all of you and hope that you find peace. Take comfort in the great memories you have of Mark and cherish each other. Much love and respect, Gary and Marlene (Bishop) Maddison.

The world is a lesser place without you Mark. You were a great friend, father, husband, soldier and leader. You had a great sense of humor and knew more jokes than any other person I've ever met. You always had your friends' backs and would stand up to bullies to protect the defenseless. You sacrificed so much for your country, family and friends. We owe you a debt of gratitude. Godspeed.

I am so saddened to hear of the loss of a very true friend. My sincere condolences and fervent prayers for strength go out to Mark's family. Know that Col Glenn is in a far better place than we are. I'll see you again Sir!

I will forever remember Mark for his unwitting nerve to be around the Johanson/Bergman family. For all the stories we told, he was steadfast in love and it was an honor to be around him. He was sacrificial, and undeserving of his illness. He loved a beautiful woman and their 3 children whom he adored.

I remember that smile when Mark came into our dorm room a ULowell 35 years ago. He was wearing fatigues and carrying a footlocker on his shoulder. We bonded over Led Zeppelin and love of sarcasm. Making each other laugh was our goal for the next 4 years. I can still recall some of his best jokes and laugh out loud today. We had tons of adventures, two poorly planned trips to Montreal, and even went to a class or two. A true Patriot who loved his family! You will be missed, but never forgotten.
