Osprey Suomi SMG Book Review

Osprey Publishing “Weapon” series is an excellent primer for those who want a book on a particular weapon system, but don’t want an overly in-depth version more appropriate for research purposes. The books aren’t intended to make you an expert on any particular weapon but do greatly improve your knowledge of a particular one when it comes to history, design, usage, and current application. This sort of approach to small arms literature isn’t new, Ballentine Books having pioneered it in the 1960s and 70s. Both publishing companies got their name for starting out with books on individual battles, then moving on to weapons. However with Osprey, the company is really getting into some depth with each particular weapon, and hopefully will expand it in the future.

In this edition by Leroy Thompson, the Finnish Suomi Submachine Gun is covered in 77 pages of text, photographs, design layouts, and artist renditions of battle scenes. Thompson covers the operational requirements for the Suomi KP/-31 in the early 1920s and 30s beginning with the KP/-26 from designer Aimo Lahti. Initially, the submachine was quite costly to produce, even incorporating a sort of receiver tube cap that could be rotated to change the rate of fire. Thompson discusses the various design variations that existed, to include short versions, cheaper versions, a port firing version with a pistol grip and stock omitted, and even a flame thrower version.

Through studying the Suomi we learn how the submachine gun was central to the Finnish tactics of maneuver warfare in the snow, quickly encircling a Soviet element, then attacking them in sections, sking to within 50-100 meters, unloading several Suomi drums, then egressing to attack again. Being able to carry this much firepower in a small package compared to an LMG allowed the Finns to inflict heavy casualties on the Soviets who were armed with bolt action Mosin Nagants and water cooled machine guns that would have taken too long to employ against such attacks. Coupled with the Finn’s superb grasp of fighting in winter warfare, the Soviets suffered a large amount of casualties compared to what was inflicted against the Finns. Fighting in the snow and the cold brings a completely different skill set than fighting in moderate temperatures. Simple tasks become impossible and hard tasks can almost not be achieved due to the severe cold.

Thompson goes to great lengths throughout the book to point out the dramatic difference between pre and during Second World War submachine gun employment and what we are used to today. Even comparing the Suomi to similar open bolt, wood stock, select-fire submachine guns of its era there was a huge difference in the way that the Finns treated and employed their submachine guns. From the uncommon accuracy, the ability to quickly change barrels, and the employment of the submachine as a precision weapon, how the Suomi was utilized is very different than how U.S. forces used the Thompson, or the Italians the Beretta M38A. In fact, because the Soviets learned through so many casualties from the dreaded Suomi, they took the concept of a cheaply manufactured submachine gun as the concept basis for the PPSh-41 submachine, manufactured with similar cheaper processes and arming entire platoons of soldiers. The irony here is that with the PPs-43, the Finns copied it as the KP m/44 with the ability to use 71 round drum magazines.

I will say that I found sources quoted from the internet as a first and somewhat surprising when it comes to actually reading books. Forgotten Weapons is even quoted as an example of the flame-thrower Suomi variant. In fact, of 34 entries listed in the bibliography, 17 are online entries, either magazines online, forums, or even blogs like Forgotten Weapons and Weapons Man. At first glance this would appear to be badly researched, but upon second thought, there really aren’t any books wholly dedicated to the Suomi submachine in the English language. So I can’t really blame the author for citing from the internet when there isn’t anything in physical print. One point I will dig Osprey on is the editing style. Whomever edited the book must have forgot to change Thompson’s third person to first person, or vice versa. He started off in the third person as “the author” when dicussing his personal experiences with the Suomi, then switches to the first person as “I” later on. It doesn’t change the material but is a little bit odd as a reader. In addition he talks about Soviet casualties in a somewhat lackadaisical manner more conducive to a forum or blog than printed material. It isn’t all the time but it comes through occasionally.

They say that the internet is a mile wide but only an inch deep. When it comes to studying small arms, I can certainly agree with this statement. Although there are numerous English language information outlets online that cover the Suomi, many even mentioned in Thompson’s book, none of them will come close to the overall depth and coverage that Thompson brings to bear. In fact, I would venture to say that the only way to have prior knowledge of the Suomi is if one was a student of the Finnish Winter and Continuation wars and even then, this book would still run laps around that knowledge when it comes to the submachine gun. Another important point I would like to mention is that even though this is just an Osprey Weapon series publication, it appears that this is only the second English language book to be published just about the Suomi. Michael Heidler published a dual German/English book on the Suomi that is much more exhaustive than the Osprey if readers are interested in a very in-depth publication on the submachine gun.

You can purchase this book through Amazon for $20.00 paperback, or $8.79 for Kindle.

    I am a great fan of the Osprey. I find them informative, useful and interesting. (e.g. from the Osprey book on the RPG I found out that the Chinese version has two sets of ranging stadia, one based on the average height of a NATO tank, the other based on the average height of a Soviet tank . . . ) However an important caveat, whatever the subject matter, the more you know about the subject the less useful they are. As the article says; they are a primer for interested parties and not a resource for experts. And they are not necessarily perfect; I’ve picked on the odd boo-boo here and there.

    That said I would almost certainly buy the Osprey on the Soumi; I know virtually nothing about the weapon, and I’ve Leroy Thompson an interesting writer, I always enjoyed his books and his articles in gun-magazines.

    The Osprey books are typically great, though with some poor editing and the occasional sloppy mistake.

    That being said, there is another book in English (and German) on the Osprey, by Michael Heidler.

    The name of the gun and the nation is Suomi, not Soumi 😉

    • I don’t know how that got by me, when I even spelt it correct in the title. I swear I read that whole book cover to cover and didn’t notice I typed it incorrectly 🙁

    Another great book by Leroy Thompson – author of over 50 books and over 3,000 gun & defense industry magazine articles over a 40 year period. I can’t wait to get mine!

  • Thank you so much for pointing that out, I’ll be adding that to the review. I did a search on the Suomi for books and couldn’t find anything at all.

    Suomi was basis for PPD-34 (not for PPSh-41 as is stated), so the lesson was much older than the Winter war.
    And there is typo in PPS-43.

    • Correct on the PPS-43 typo, I’ll get that fixed.
      Maybe I should have worded that better. The PPD-34 was although reliable, it was heavy and costly to manufacture. The Soviets took the lessons that they learned from the Soumi, realizing they needed a cheaper, lighter, and better submachine gun than the PPD-34, and thus incorporated those lessons into the PPSh-41. Arguably, the PPSh-41 might never have been conceived had the Winter War never took place, and the Soviets took horrendous casualties.

    Have not encountered a single one of the Osprey books worthy of adding to my personal library as a permanent fixture yet. They are about suitable for public library holdings aimed at the grade-school population, at best. If you’ve got a kid or niece/nephew who’s between 6-14 & exhibits interest on the topic, they’d make good gifts. JMNSHO
