Not all vehicles used by the military are obviously military. For trips to Snowdonia we always used white minibuses, as I said it's more for adventure training rather than military training
A very sad event, the loss of any training recruit, but then any death of anyone military personnel is always sad.
It must raise the question of how these training sorties are organised and run, even though the lads and lasses need to train in extreme environments and conditions, they need to be brought up to the mark sensibly and with the right support to prevent any fatalities.
Though the armed forces do tend to use white, unmarked, mini buses, I it find surprising, because I've seen quite a few military vehicles, in camouflage, when I travel to North Wales and Snowdonia.
There are quite a few unsigned camps/bases in Snowdonia, and also a few signposted, particularly Capel Curig Camp on the A5, which you can't miss when driving past.
