This is strange posturing. Anti tanks rockets won't make a difference.
Why not? During an invasion the Russian troops would need to be able to move around Ukraine somehow.
Sure, but I expect any current generation Ukraine ATGM to match the UK stock.
The UK is like the irritating posturing, strutting wee scrote at school who everyone is dying to punch out. But who always hangs about with the biggest boy in the form, so no-one dares touch him.
