One side in the India-Pakistan War invested heavily in drone capabilities over the last decade. The other did not.

The Indian army said on Saturday that Pakistan was continuing its "blatant escalation" with drone strikes and using other munitions along India's western border, and its "enemy designs" would be thwarted.

The frontier between arch-foes India and Pakistan was peaceful and had the "first calm night in recent days", the Indian army said Monday, after a surprise weekend ceasefire.
