muster call การใช้

• Another source was " muster calls ", non-periodical strength reports of the personnel ready for duty.
• Muster calls are the main source for the strength of armies before the 19th century, but by their own nature they lack continuity and are ill suited for long time period analysis.
• They are especially useful to study army costs, but they are not so reliable as muster calls as they only show payments, not real soldiers ready for duty, and before the 19th century " ghost soldiers ", men falsely enlisted by officers in order to get the fees for themselves, were a very common occurrence.
