Ukraine’s General Staff wrote about this, referring to the UK Ministry of Defense.
On January 15, Britain confirmed plans to transfer a squadron of 14 Challenger 2 tanks to Ukraine, a battery of eight AS90 self-propelled guns at “high readiness” and two batteries at “varying states of readiness.”
A group of Ukrainian military personnel arrived in Britain for training on AS90 self-propelled guns at the beginning of February. The Ukrainian artillery soldiers have backgrounds ranging from experienced artillery soldiers to little or no military experience.
