A Little Something about “Jägare”

While the Finnish and Swedish armed forces in general are rather similar, the languages they speak differ. And not only in the obvious difference between Swedish and Finnish (and Swedish), but key words and phrases differ as well. While the difference between engineers (ingenjörer) and pioneers (pioneerit) is largely quaint and shouldn’t cause too much trouble, the word jaeger (jägare/jääkäri) is another matter completely. In the Finnish Defence Forces the word has several different, sometimes slightly contradictory meanings. My personal rank is that of a jääkäri, which simply translates to private. But it is also used to describe different kinds of infantry, such as mechanised (panssarijääkäri), rangers (erikoisrajajääkäri), or urban (kaartinjääkäri). Historically, it has also described the original Finnish jääkärit trained in Germany during WWI.

In Swedish the word has much narrower use, describing ranger-style army special forces. However, there has also been a significant shift in both the mission and tactics used compared to the pre-2000 Swedish jägare, so when Swedish defence blogger Jägarchefen wrote a post describing the modern Arméns Jägarbataljon, I asked for permission to run the translated version as a guest post.


An interesting discussion took place on Twitter 10FEB2018, a discussion I followed from the side. Part of the discussion came to focus on how airmobile and ranger units could be used in an armed conflict. Airmobile units I will happily leave to the professional officers of the 31. Battalion to recount. However, it might be suitable to describe how today’s, sole, ranger battalion would operate in, i.e. Arméns Jägarbataljon (AJB, the Swedish Army Ranger Battalion), the wartime 193. Ranger Battalion.

The, unfortunately, stubborn picture in the Swedish Defence Forces in general and in the Army in particular regarding how the rangers fight is based on how the Norrlandsjägarbataljon’s (NjBat’s) and Jägarbataljon syd (Jbat Syd) would have fought during the 1980’s and 1990’s. Their battle would take the form of direct action followed by a decisive battle behind enemy lines. In other words, the battalions were given a geographical area, which was further divided into company-, platoon-, and squad areas. Within these the so called direct action would take place, simply put different forms of ambushes against predetermined targets such as supply vehicles during a prolonged time. The battle would then transform to interdiction once the divisions of the Swedish Army would launch their all-out offensive aimed at destroying the enemy formations. During this interdiction-phase the ranger battalion would stop all enemy movements within their given area, and thereby support the main corps-level effort.

The overarching thought with NJbat and Jbat Syd was partly to ‘tax’ the predetermined targets, and partly to create a threat that the enemy would need to allocate resources to counter, thereby reducing the units available at the actual frontline. Together, this would allow for own combat units to, possibly, achieve numerical superiority in their battles.

This idea is unfortunately very much alive in schools, centras, and commands. In different kinds of wargames the symbol for ranger battalion is often placed in a number of squares on the map, where it then spends the rest of the time while the tactics is played out elsewhere. In principle this is correct for the tactics of days gone by, but in no way corresponding to today’s sole ranger battalion. Today’s ranger battalion is in no way tied to a certain geographical area as NjBat or Jbat Syd were, but is instead used where the capabilities of the unit provides the greatest benefit to the common fight.

How does the operations then benefit the common fight? Before solving more complex missions, i.e. those on high tactical, operational, or strategic levels, a thorough analysis of the coming enemy is always conducted. Own vulnerabilities are always identified, so that they can be protected, but also the vulnerabilities of the adversary is mapped out. These include so called critical vulnerabilities, which might have to be influenced. Obviously, the adversary will in some cases, like us, be aware of his vulnerabilities, while in other cases, like us, he will be unaware of these. If he is aware of his critical vulnerabilities, he will naturaly allocate resources to protect these.

If these critical vulnerabilities are influenced they will create ripples, which makes other parts of the enemy vulnerable. An interesting fact, which often but not always hold true, is that the critical vulnerabilities found deep within terrain held by the opposing force usually create bigger ripple effects if influenced than those closer to the frontline. It is these targets, critical vulnerabilities deep behind enemy lines, that today’s Swedish Ranger Battalion is set to work against. This also means that the targets might be highly prioritised, and that the enemy might allocate sophisticated and sometimes extensive resources to their protection.

As such, today’s sole ranger battalion is miles apart from its predecessors. The unit isn’t tied to specific geographic areas, but is used deep behind enemy lines against the critical vulnerabilities that have been identified as having the potential to affect the outcome of the battle. How the battle is fought and with what unit size is not defined in set doctrinal rules, but rather decided on the basis of the specific target in question (the critical vulnerability). It follows that the unit isn’t meant to be used in the role it’s often wargamed in in schools, centras, and commands, i.e. direct action along roads during prolonged times.

A secondary effect of influencing the critical vulnerabilities is that the enemy will have to allocate resources to protect their rear areas, perhaps in even larger numbers than before. This is due to the fact that it isn’t possible to predict where and how the rangers will operate in the same way as earlier. This will indirectly tie down resources to counter the threat and create a more beneficial numerical situation along the frontline, in addition to the direct effect on the critical vulnerabilities.

I will argue that the lack of this knowledge means future higher level officers, and to a certain extent current ones, will fail to understand how a highly capable instrument should be used in their planning and in the conduct of the battle. An instrument that in my opinion can play a part in deciding the outcome of the common fight.

Finally, it should be noted that this post is written in a very general way to not disclose strengths, weaknesses, or tactics. As such, no classified information is touched upon in this post.

Return to Gävle


Readers of the blog will remember the Gävle-incident in July, when Swedish media reported that an unidentified object had been recorded by a survey vessel in the port of Gävle. Back then I argued that the likely culprit was a swimmer delivery vehicle from the Swedish Defence Forces. The case then more or less died down, with the Swedish Defence Forces eventually issuing a (half-hearted?) denial that they had operated in the area at the time.

Today the story resurfaced after Swedish media published news about a private report detailing that the incident should be classified as a “serious intentional violation”, and that foreign underwater activity had taken place in the port. The two authors of the report are a far cry from your everyday happy blogger, and consist of Nils-Ove Jansson (former deputy chief of the Swedish military intelligence agency MUST and with work experience in naval intelligence analysis) as well as Nils Engström (retired naval officer). While they are unable to determine the nationality of the intruder, they point to “certain similarities” between the pictures and Triton-NN, a Russian SDV. The report has been sent to the Swedish Defence Forces and the Port Authority of Gävle.

What makes the whole thing more interesting is the comment by the Swedish Defence Forces when confronted with the findings. To Swedish Daily SvD they point to their own investigation, which they “are confident in”, and conclude that there are “no indications of this being foreign underwater activity”.

Note choice word “foreign”.

Naturally, it is possible (even likely) that there are details not mentioned in the media abstract of the report (which certainly would make for interesting reading), but when one put the pieces together it does seem that we have a situation where:

  • Two independent experts have confirmed the presence of underwater activity in Gävle,
  • The Swedish Defence Forces denies it is the work of foreign special forces,
  • We know from before that the Swedish Defence Forces has a policy of not commenting on issues dealing with how their own special forces train or operate.

As such, I would still argue that the most likely explanation is a Swedish SDV with associated special forces either training or performing a live mission in the port.

The sources are found here and here (both paywalled), with a shorter version for free here.

An SDV goes Gävle

So it seems that approximately once a year there is some kind of more serious unexplained underwater activity in Finnish or Swedish waters. On 29 June it was the port of Gävle’s turn to be at the centre of attention.

Following dredging works in the main sea lane leading into the port, a hydrographic survey was made. As is usually the case when measuring small areas where high precision is needed, a measuring frame was pulled under the water at the correct depth (for simplicity, think of a welded frame being pulled at a constant depth, indicating if it hits something). At the very inlet of the port this indicated some kind of “anomaly”, and it was decided to scan the plot with a multibeam sonar. The area was then scanned between 11:00 and noon, after which followed a lunch break during which the scans were studied closer. It was then that the crew thought that the shape looked “boat like”, and after lunch the area was rescanned around 13:00. The “anomaly” was still there, and the survey vessel ran a few laps around it. The vessel then went to get divers, and when the divers arrived around 14:00 the anomaly wasn’t visible on the multibeam sonar any longer.

The object is described as around 12 meters in length, and roughly 3 meters high.

It does seem clear that it was some kind of a underwater vehicle. It was observed by professionals, using proper equipment, and observed numerous times before disappearing. It should also be noted that the location meant that if it had been there for any longer periods of time, it would have been hit by a passing merchant vessel.

The obvious next question is what kind of a vessel it could have been. It does seem to feature a quite pronounced passenger bay, meaning that it is likely a ‘wet’ swimmer delivery vehicle, SDV, in which divers sit with their gear on, and not a ‘proper’ midget submarine. There are two (likely) operators of these in the Baltic Sea: Russia, and Sweden.

Russia (probably) uses the Triton-NN, which rose to fame during the Swedish sub-hunt a few years back when it featured heavily in the speculations. Here there’s the obvious point that Gävle was mentioned by Gerasimov in April as part of a staging area, as discussed on the blog earlier, and as such it is likely the target of some form of intelligence gathering efforts.

A more likely candidate, however, seems to be the Swedish JFD SEAL Carrier, which the company has confirmed it has delivered to the Swedish Defence Forces. The likely user is the combat divers Attackdykarna, thought within the Swedish Defence Forces there are also other potential operators under the surface, such as the special forces (SOG), underwater clearance teams (Röjdykare), and even certain army engineers practice diving.

Compare the general dimensions of the SEAL Carrier to the skiss above. The vessel is 10,5 m long, with a width of 2,21 m. The stern is sloping (tumblehome, left side of the picture), while the bow is more sharply built with the crew/passenger compartment being the open bay close to the bow. Perhaps the most significant feature is the round object to the left of the centreline just aft of the passenger compartment. This location matches the location of the snorkel on the SEAL Carrier. As it happens, the Triton NN is more or less an mirror-image of this design, with a car-like bow and a passenger-compartment towards the (straight) stern. There is also a snorkel mounted on the right-side in front of the passenger compartment, but the proportions doesn’t seem to match as well.

As such, my impression is that this is an example of the Swedish Navy’s combat divers being accidentally found during one of their unannounced exercises. As such, the outcome of the incident is probably not much worse than that someone has to buy someone else a round of drinks. Keep calm, and carry on!
