wire obstacles are used to prevent enemy forces from moving in the front of their own positions and on their own flanks.
when creating wire barriers, width comes before depth, but depth comes before height.
wire obstacles are to be installation inside one's personal visible range, however outside of the enemy's hand grenade throwing range, in order that the enemy can not throw hand grenades into one's own positions.
therefore, with a 50 m roll of barbed wire round 10 m in width may be blocked, with a roll of S-wire, of which 3 rolls are wanted for the necessary height, around 12 m wire cutters.
wire barriers are alleged to hinder the enemy and create time for one's personal troops for fireplace fighting; Grass fence.
At crawl and knee height, they significantly hinder the enemy in advance and create time to fight him.
excessive cord barriers are quickly damaged by artillery hearth, low depth obstacles even with gaps prevent after artillery fire.
The wire should no longer be stretched too tight, otherwise it could break in the cold or when bombarded.
similarly, as with barriers in general, there's the principle that wire obstacles must always be monitored by your own forces or their fireplace, in any other case they can be evacuated by the enemy and thus lose their purpose.
