Well for your TO&E the US and others have at least one AT wpn per Squad. The increase in standoff range e.g. 600m makes a big different in not only the defense. But even offense, i.e. dismount AT ambushes and even direct attacks on Russian armor. Have done this in training a number of times. A dismounted night raid on enemy AFVs can be very effective. Using a number of types of manpack AT weapons. Even our Dragon had a min. rg. of like 65m, IIRC. LAWs were shorter, IIRC 25m. Plus even demo charges. Can be used on an "close assault" attack on AFVs.
So as I have said before a Squad would have one MAW, plus many LAWs were issued as well. So the NLAW is much more effective than our Dragon. Even if it's range is shorter.
Spreading your troops out is always a good idea. But generally Squads and their Fire Tms will be somewhere closer to each other for command & control. Plus mutual fire support. Dispersing based on terrain and situation.
From a Plt Ldr's or Co Cdrs standpoint. In the defense as usual set up your weapons including AT with interlocking sectors of fire. In your tactical area of responsibility[TOAR]/assigned sector. Trying to get flanking shots on enemy AFVs from your various AT positions/locations.
Also note, 600m or 1000m can be covered fairly quickly by advancing AFVs based on the terrain. So you generally have to try to engage your targets at longer range. Making every shot count. Is you take out a number of their advancing AFVs, they may just try to break contact. And maneuver out of your FOF/LOS.
And if possible call-in FA & CAS … Even the new AT weapons still have to be part of a combined arms team. With mutual support between all the arms/weapons in the team.
As I posted on another thread :
Well with the long range of the TOW, 3750m + then and now with powerful man-packed Infantry AT weapons, e.g. Javelin NLAW, etc.. Gives the Infantry some very effective AT weapons. And yes, as a Cold War Warrior, the new Infantry AT weapons are nothing short of Sci-fi…
We always organized Squad sized AT ambushes if the situation required it. And yes demo could be part of that Squad.
In the 101 we had an entire AT Co. with Jeep mounted TOWs. I AT Co. per Bn. And in Mech Cos. there was an organic M901 ITV Section of 2. Plus a Bn M901 ITV Co. Infantry squads each had a Dragon plus LAWs etc. if need be.
Gunships with AT weapons which started during Vietnam were designed to take on the USSR/WP hordes crossing the IGB. The USAF A-10 was specifically designed for tank killing these hordes. And even Joint Air Attack Teams[JAAT] using Gunships[AH-1s then later AH-64s] & A-10s together. Was a tactic specifically designed to decimate those USSR/WP armor/mech units.
Russian poor overall lack of tactical expertise makes Ukrainian AT weapons that much more effective.
Do you really think a U.S. or UK armored brigade would be having this much difficulty with infantry AT weapons? Between the battlefield intelligence net, drones, helicopter support, artillery missions
Unless the enemy is very well trained, armed, skilled and lead. The US/UK forces will always have an edge. That is why the local forces had to go guerilla to even survive.
But even the Iraqis and Taliban did KO some US/UK, etc., AFVs. But the numbers were small. The US M1 TUSK upgrade in urban or closed terrain made it that much harder for enemy man-packed AT weapons to be effective. There was a similar upgrade to the M2 Bradley IFV.
As always is comes down to the troops and crews behind those weapons. This again is made clear with the war in Ukrainian.
