Re: 13,000 laptops
If it's the MoD there's a very limited range available in the IT catalogue so you're not getting a Surface Pro. On the plus side even the lowest spec models are powerful enough to run the required applications, which is an improvement.
My understanding is that MoD were planning on rolling out more laptops plus docking stations to replace desktops, but COVID-19 happened first delaying things. So the ~10,000 they've acquired are probably unrelated to the illness itself more the new financial year kicking in.
