# Strength and Weight Management (UFOAI)

## Encumbrance

The maximum weight a soldier can carry is equal to their strength stat in kilograms. A soldier with a strength stat of 34 will be able to carry up to 34kgs. However, a soldier will become encumbered if they carry more than 50% of their maximum weight. So a soldier with a strength stat of 34 will see his TUs decrease if he is carrying more than 17kgs. A soldier will also receive increased TUs if they are carrying less than 20% of their maximum weight.

A soldier's TUs are calculated using the following equation:

```39 * ENCUMBRANCE_MODIFIER + SPEED * 20 / 100
```

The ENCUMBRANCE_MODIFIER depends on the weight carried:

• 1.0 = 20% or less of maximum weight
• 0.7 = 20-50% of maximum weight
• 0.4 = 50% or more of maximum weight

## Strength Training

Soldiers earn experience in the strength stat by carrying equipment into missions. The more equipment carried, the more experience the soldier will gain, up to a maximum of 125 points per mission. The formula for experience points is:

```50 * (weight / strength) / ENCUMBRANCE_MODIFIER
```
