What is security for?
To prevent assassinations, prevent riots, protect one's master... They might have better training than the military, better equipment, and are more professional in some missions to protect VIPs. However, when the situation escalates into large-scale warfare, differences in specialization, training methods, and weaponry become a vulnerability.
Security forces lack heavy firepower and anti-armor capabilities. Facing artillery, they struggle to counter; against the so-called Knight Order, those Sentry Mecha paired with two Ranger class Knight Titans charging at them, they are at an overall disadvantage.
Their numbers are far fewer than the opposing side. Under the onslaught of the enemy's vast expendable troops and withstanding artillery barrage, as well as targeted assaults by Knight Titans leading numerous Sentry Mecha, the defense line of Gu's Security was continuously compressed and breached.
The situation quickly became perilous.
