That is exactly correct. I know something about Chechens personally. They are not Arab but Caucasian, and mostly Sunni. They have been fighting the Russians for nearly two hundred years, and very nearly defeated the Tzars in the mid-nineteenth century under their legendary chieftan, Shamil, the Lion of Daghestan (pictured below).
Most people make the mistake of assuming that their conflict with Russia was about religion, i.e. Muslim vs. Orthodox Christian, when it fact their motivations were and remain entirely nationalistic. Chechens are bold, fierce fighters and will typically fight to the death. Most Arabs are afraid of them. They were so tough that Stalin had them deported wholesale, along with the Crimean Tatars, to Siberia. Those that escaped ended up in Jordan, where they and their descendants essentially constitute the cream of the current Jordanian Army Officer Corps.
The bottom line is that if our troops are running into these guys, then they truly have their hands full.
