 British Helmet, Combat Assault, Mk7 by Philip's Military Helmets
The British operations during Operation Herrick in Afghanistan (2002-2014) highlighted a serious and urgent problem faced by soldiers wearing the Mk6 and Mk6A helmets. In Afghanistan, the terrain and conditions meant that foot patrols were far more common than in Iraq, where mounted patrols were the rule rather than the exception. Firefight engagements were very common and British soldiers were frequently having to fight the Taliban while crawling along the ground for cover. However, the Mk6 and 6A helmet did not allow troops with body armour to lie flat and shoot straight, without the rear rim digging into the body armour and tipping the front rim over their eyes. This drastically reduced their ability to aim and fire accurately, thus exposing the solders to unnecessary risks and reducing the effectiveness of the British forces on the ground. This led to an Urgent Operational Requirement (UOR) by the Ministry of the Defence for the introduction of a new helmet design to counter the serious flaw of the Mk6/6A helmet.
The new helmet design was unveiled at the Defence Vehicle Dynamics (DVD) equipment show in June 2009. It was given the official designation “HELMET, COMBAT ASSAULT MK7” and was manufactured by NP Aerospace. Over 10,000 sets of the enhanced Mk7 helmets were produced under initial contracts worth around £16m, with the first batch 5000 helmets being quickly supplied to frontline troops. The Mk7 helmet is lighter than its predecessor,1 kg instead of 1.5 kg for the Mk6A helmet, and it has a more stable five-point chinstrap. It is produced in a new colour, tan, unlike the Mk 6A (black) and Mk6 (olive green) and the outer shell has a rough texture. The shell is perforated 7 times, with 5 holes to fix the 5-point chinstrap and 2 holes on top to hold the poly-ethylene layer inside the shell (as in the Mk6 helmet). The ballistic protection is similar that of the M6A, measured at V50 - 650 m/s. (V50 is the mean penetration velocity. At this velocity, half (50%) of projectiles are expected to penetrate the shell). The liner is quite like that of the Mk6A at first glance. Being an interim helmet design, the Mk7 helmet is already being replaced by the Revision Batlskin Cobra Plus helmet system, which was acquired through the Virtus Programme. The first deliveries of Revision Batlskin Cobra Plus helmets was planned for quick shipment in Autumn 2015, with first-recipient troops being fielded with the new helmets in early 2016.
