the 10 RW is the new helmet so no new tender exists but a number of upgrades have been requested that would bring us inline with the shiney French variant.
The real issue we face is something called MAHIS which is the military aviation helmet impact standard or double impact protection standard this means helmet design is complex for us but neither Mk4 or MK10 meet it! So this will be next to address!
Either Way MK10 is a more modern beast then the Mk4 family and a step in the right direction, now it needs some toys to make it standout from the crowd, some of those things would be a goggle solution and visor employment with NVD!
