Let's see...
Land Warrior - 16 lbs
Historical loadouts:
WW1 French infantry - 85 lbs
French Foreign Legion during the North African campaigns - 100 lbs
WW2 British infantry - 70 - 90 lbs
1983 Grenada Campaign, US Rangers - 167 lbs
Current US Soldier loadout - nearly 80 lbs. That's with body armor, weapon, ammo, and other equipment, and excluding Land Warrior.

From a study (man, we're really good at studies it seems):
Given that the body armor can weigh anywhere between 15.7 lbs to 23.9 lbs? Yeah, that's half your combat weight right there.
And of course:

From a study (man, we're really good at studies it seems):
A fighting load is everything worn or carried except a rucksack and should be held to less than 48 pounds, according to the field manual. The next level, approach march load, adds a light rucksack and should not exceed 72 pounds. In the worst-case scenario, emergency approach march loads require a larger rucksack, raising the total weight to 120-150 pounds.
Given that the body armor can weigh anywhere between 15.7 lbs to 23.9 lbs? Yeah, that's half your combat weight right there.
And of course:
After reviewing the data, the average rifleman's fighting load was 63 pounds, which meant he was carrying on average 36 percent of his body weight before strapping on a rucksack. The average approach march load was 96 pounds or 55 percent of average rifleman's body weight, and the emergency approach march load average was 127 pounds or 71 percent of average rifleman's body weight.
