The basic compoments of attack are:
1. The attack occuring
This is the final stage of attack. It happens when you already have necessary manpower and basic or advanced weapons and will and strategy to carry out attack.
2. The building of attack
This is divided on 4 sections:
A. Building of strategy (through leadership's intelligence)
B. Building of weapons (by having both basic workers and those intelligent ones who develop advanced technology)
C. Building of manpower (increasing number of people in military)
D. Building of will (through leadership's guidance)
All of these are necessary to carry out attack with your military.
3. Protecting 1 and 2
In military strategy, it is important to more than just build attack, but also to protect attack and protect those components which build attack, such as leadership which develops will and strategy, workers who support military, and military itself needs to be protected from being destroyed before it can attack.
So the basics are:
1. The attack
2. Building of attack
3. Protecting the attack and protecting the building of attack.
Some militaries in history have abandoned 3 and just went with attack and building of attack, such as those militaries which had no much military production to protect, usually guerilla militaries who focused on just attack and building of attack, without building protections of workers and factories and even abandoning the protection of bases, as same was unnecesarry due to nature of the strategy which was focused on attacking and building attack, and avoiding detection.
Additionally, many small militaries abandon 3 because it tends to be unrealistic, as they lack technology to protect factories and workers from an attack of an advanced country, thus they focus on attack and building of attack alone.
Additionally, they often get weapons from other countries, which in a way negates their need to protect their own weapon producers.
