Hot and humid. If your fatigues (uniform) weren't soaked in sweat, better see a medic, something might be wrong with your sweat glands.

Vietnam's weather is a tropical kind of climate so I guess it would be sunny and rainy a lot I don't think it snows there though.

Hanoi doesn't. Since Hanoi is part of north Vietnam, this city features a subtropical climate. Temperature can drop down to 3oC in winter. In additional, northern Vietnam is the only major region in southeast Asia that has subtropical climate.
Vietnam's climate is dictated by two monsoon seasons -- the southwest monsoon from March or April to September and the northeast monsoon from October to late March or early April. Leandra Kramer
