Howdy Rotor,
I used to know a guy many, many moons ago who oft times during normal conversation with him, his response's would now and again become........'sharper' edged than they needed to be. He generally didn't mean to be so 'hard', but sometimes it just came out that way. He was a close friend, and a good man. We had an agreement he and I, that when he started to 'sway' in that conversational direction I would simply say to him "Jimbo, your slip showing". And he would silently get the point and know that our friendship was still intact and healthy.
Something that was important to both of us.
First off, my apologies for not knowing that you had convoy experience too. I probably should have been able to put two and two together after you shared a little of your experience with me about the HEMTT's...my bad!

I'll know better next time. Promise.
And you know what, next time is right now!
Your explanation of the convoy arrangement you participated in was very helpful. Not quite sure I got
all the lingo, but I think I can extrapolate. I can only assume your multiple convoy duties were performed during peacetime so I would like to know if there is a different deployment of vehicles depending upon the 'threat' level. Your description makes sense as to easy access to the tanker trucks in regards to the
convoys needs. That adds up and seems logical.
I was just trying to ascertain if the same arrangement might be employed during wartime.
Now, as to your hypothetical use of alien spacecraft to attack the middle of the convoy to get at the tankers......
I'm going to play a little
friendly 'devil's advocate' for a spell and apply a little Sun Tzu if it's alright?
If I was waiting alongside a road to ambush a passing convoy of trucks, and wanted to inflict as much damage as I could, just one of the methods I might employ would be to stay hidden and
wait until the middle of the convoy (which is where the tankers are positioned) comes passing by and then hit the highly volatile tanker trucks with a heavy barrage of rockets or RPG's. I wouldn't have to strike all of the tanker trucks, probably only two or three to create an immediate roadblock and a situation of bedlam. At that point, especially with so many vehicles both behind, and in front of, the tanker element. I would have already positioned the main assault force further forward and down range of the diversionary tanker attack and wait until the word got back to the front elements who would send at least some of their 'protection' to assist the established threat at the tanker element to their rear. The rear element at this juncture could/would also respond to the threat at the middle. I would have very little concern for the rear element because it's
only options would be to respond or not to respond. Either way, they're not going anywhere until the engagement is
over.
Meanwhile my main force would attack the now weakened front element and proceed to 're-requisition' as much as I could get away with. Having done this, I would then withdraw my diversionary force fighting a retreating action with a second emplaced force covering my retreat in case of pursuit by the convoy defenses.
I'm probably dead wrong about this, and it wouldn't work at all.
Maybe 'animal' can poke some holes in my scenario we can all peek through. #:-)

Tread.
