Not just a march-out, but a throw-out.
Portadown Way JHQ backed onto the woods, deciduous mostly. Every autumn, prodigious leaf fall ended up inthe back gardens. SROs [or whatever] forbad householders from returning the leaves whence they came ...... the Forstmeister was adamant. Neither could you bonfire them.
However, march-out demanded a tidy and leafless garden.
Hence furtive excursions at first light or dusk, bearing sacks and sacks of leaf sweepings, to be SCATTERED not dumped in tell-tale heaps.
Like so much of service life, you couldn't make it up.
