I think this report refers to a number of things that are going on, but numbers are yet to be announced. There was an agreement earlier in the year, a helicopter trust fund, where a number of NATO nations would foot the bill to upgrade helicopters (fit them with defensive aids, NVGs, etc) from countries like Bulgaria, Czech Republic, Romania and Poland so that they would be able to deploy in Afghanistan with their own crews. The UK is also still due to send its six Merlins HC3As and certainly not 30 helicopters. Several other countries have offered extra helicopters, although some of these won't end up in Helmand.
