As Estonian I can say that due to our joining with NATO (now) 99 percent of effort is commited to joint operations with Allies. This means that platoon and company-sized units are trained to work as part of bigger Allied forces formation (company, batallion) against insurgents. This tactics changes 180 degrees from guerilla war. There was proposal that Ministry of defence chould produce side mines against armoured vechicles (that Finnish deep operations units use, kind of side mines used by Iraqi insurgents), latter was chocked. You can say that at least lessons are known, but you have to also drill this during conscription. This is not done. Picture of war in small country depens A LOT wether this is done with the help of allies or alone.

This case study is part of topic "how decisions are done."

If I remember correctly, US train and equip program was started to make Georgian army able to fight against Chechen isurgents that inflitreted Kodori gorge and established safe haven there. Russians were complaining this all the time and bombed Georgian territory.

Even US officer proposed deep operations concept.
