True/False: Hand measurements of angular deviation are the same for all observers.

Hand measurements of angular deviation can vary between observers due to several factors, including the perspective from which they take the measurement and individual differences in their ability to estimate angles. Each observer may interpret and measure angular deviation based on their own viewpoint, equipment used (like protractors or compass), and personal skill in estimating angles, meaning that consistent measurements cannot be guaranteed across different observers.

In any situation requiring accurate angular measurements, such as operations in fire support, ensuring uniformity and precision is critical. Consequently, relying on hand measurements taken by different observers could lead to discrepancies, which may impact targeting or coordination. Therefore, the statement is indeed false, as hand measurements of angular deviation are not the same for all observers.
