Although the Molotov cocktail is quite primitive, it's merely a bottle meant for throwing, but its effectiveness is no less than other equipment.
The key is its simplicity.
Other weapons may require considerations of design, gunpowder, and other technologies beyond the reach of ordinary people.
The Molotov cocktail is just a glass bottle, some gasoline, and a cloth stuffed in the bottle neck.
Shire took only a few minutes to craft a Molotov cocktail. He lit the cloth and hurled it far away. With a crisp sound, flames erupted instantly at the point of impact.
"This is a Molotov cocktail; it will make an excellent night battle equipment." Shire waved his hand towards the flames: "Infantry can throw it into enemy trenches, and tanks can thus know the layout of the trenches."
Colonel Estiny and Tijani, who stood watching the scene, were dumbfounded.
Such a simple combination could produce effects similar to or even better than a grenade, but only Shire could have thought of it.
