I bet the British have little access to that equipment, their government has underfunded them from the start.
Possible, and the Buffalo is less effective in Afghanistan than in Iraq (terrain and all). Still, a better option, I would think, is “recon by fire.” But, each unit has their own way of doing things and I have no doubt that they do what is best in their AO.
That aside... I have heard and seen too many cases of a soldier getting killed within weeks or days of redeploying. It is sad, but it shows that the enemy is smart. Attacks tend to increase as units change out.
