Thanks for all the kind words, glad everyone enjoyed it. Really want to get more battle reports written (mainly so I get to play some more). I'm planning a scenario pack to be this year's Christmas special (details still TBA) and so hopefully I'll be able to get some battle reports of that in the next few months.
Hindsight is 20/20. I don't have military experience but I think the procedure the ADF player took would have been classed as reckless in any AAR. The vehicles were way too close together, meaning in the event of a strike both were damaged. If I had been playing (and hadn't written the scenario) I'd have probably either
a) pulled off the road into a overwatch position at a safe distance and then tried to identify if the vehicle was a threat (using the FLIR optics available on the second vehicle). If the device was spotted, the players could have declared they were waiting for engineer support (meaning they would be sat in the open and vulnerable to OPFOR attack, especially from the ratlines) or have engaged the vehicle with the M2 or MK 47 to try and detonate it (dangerous as the exact capabilities would be unknown)
b) go off road and avoid the possible threat entirely. This would slow the convoy down and might leave them exposed to enemy fire for longer but it does mean they could continue the mission. It would also be a hearts and minds disaster as the device might end up being left in place and used against local civilians
