Old school night patrolling preparation was (and I hope still is) all about no sound.
Gear tight but not to creaking point, clasps, clips, and fastenings taped to stop the inadvertent click or tap.
Zip tags removed or soft taped to stop that little ‘ting’ noise they make.
Laces tight, ends tucked away, pockets filled appropriately but with nothing rattling.
Over clothing if appropriate “non rustle”.
Footwear was always soft leather, DMS (directly molded soles), and laced, mil pattern.
As for velcro?
Who the hell thought it a great idea to fit it on combats and carrying rigs instead of straps, buckles, and press studs. Especially on pouch or pocket flaps.
Quick and reasonably secure it may be but it’s as noisy has hell in the quiet of the night.
I just can’t get my head around it.
Modern materials (well sort of modern) and no one seems to care about that ripping noise that can only be interpreted as man-made. Same moan for zips, plastic or not.
So take a look at your clothing. How much Velcro and zips have you got?
How much is essential?
Personally I change everything to plastic press studs, clips, or buttons.
Good sound discipline, together with situational awareness and careful use of cover, will serve you well if you ever have to move covertly and close aboard to “undesirables”.
