No, there were no campaigns for medals to actually be awarded, it was merely a defence force that had been raised because of the situation in the Transvaal after Vereeniging, the end game had been played out on the veldt and there were certainly many issues left to resolve, the whole country had been left in tatters.
The major issue was that everyone was armed, you can think of the Transvaal as a powder keg about to explode, with so many isolated groups of Boers and Natives quite literally at each others throats, the Northern part of the country was particularly dangerous, with the SAMIF disbanded and so very few members of the South African Constabulary to take their place.
Lord Milner was not trusted as an administrator by a great many people here in Great Britain and was, quite understandably, far less trusted in South Africa, in particular by the average Boer, simply because he had been instrumental in starting the war and bringing it to a successful conclusion for Great Britain.
He was replaced by Lord Selborne who was rather more sympathetic towards the Boers and his methods and certainly his policies were far more wise, for example, he introduced a dual language system in schools in the Transvaal and I should think just that one simple act did more than anything else to tell the average Boer that Great Britain's intention was to live on equal terms as long as the ever present racial issues were kept in check.
So you can see that there was a need for a part time defence force recruited locally, particularly as the act of disarmament had been so time consuming and there was also a fear of a nasty insurrection breaking out, moreover, I dare say it's creation was a very real saviour to so many men who had fought during the war.
