Earlier, in 2007, HGI competed against several other generator manufactures for the prestigious Ptarmigan generators job.  A requirement from the UK MoD, Ptarmigan is the British Armies Radio Relay Trunk Communication System,  in effect a mobile Local Area Network for the armed forces.

As well as the usually demanding specification and environmental conditions the real test for any supplier was to deliver in the shortest of lead times.  HGI compressed the development period into a quarter of the usual time needed.  Working with its component suppliers and other accredited bodies, HGI was able to deliver the set with its demanding military performance on time and on budget.
