The line of contact was, immediately after the ceasefire, a "relatively quiet zone with
barbed wire and lightly armed soldiers sitting in trenches", according to
Thomas de Waal. In 2016, there were around 20,000 men on each side of the heavily militarized line of contact. Since the ceasefire the line of contact had become a heavily militarized, fortified and mined
no-man's-land and a
buffer zone of
trenches. According to de Waal, it is the "most militarised zone in the wider Europe," and one of the three most militarized zones in the world (along with
Kashmir and
Korea). The line of contact was regularly monitored by a group of six
OSCE observers, headed by Andrzej Kasprzyk of Poland. There were exchanges of fire virtually on a daily basis. There had been significant violations of the ceasefire on various occasions, usually characterized by low-intensity fighting. Significant fighting
occurred in April 2016, when for the first time since the ceasefire the line of contact was shifted, though not significantly. According to Laurence Broers of
Chatham House, "Although slivers of territory changed hands for the first time since 1994, little of strategic significance appears to have altered on the ground." The 2016 clashes also marked the first time since the 1994 ceasefire that heavy
artillery was used, while the
Second Nagorno-Karabakh War saw use of heavy artillery,
armoured warfare, and
drone warfare. On October 9, 2020, when
President of Azerbaijan Ilham Aliyev addressed the nation, he stated, "There is no status quo. There is no line of contact. We smashed it." ==Impact==
