Long johns Yep you will need the at -25c
Good Winter parka and trousers
Service head gear for the unit you portray Fur cap
Belt
Gloves
Scarf or toque or both
Boots with the boots felt type ,Low boots * Modern boots are ok **
Sleeping bag
We will not let you out in the field with out any of the above as Frostbite is a real danger !!
Field Kit
Bread bag
Mess kit
water bottle +cup
Ammo pouches
Zelt
and a back back Wartime looking
*Low boots try to get 3 (Three) pairs of socks on thick wool ones
** Modern boots are ok if the look correct for the time
last year the night time temps were -17c to -30c learn the information below
LEARN IT MAY SAVE YOURS OR ANOTHERS LIFE
we are playing at war but the danger of Hypothermia and Frostbite are REAL
Normal body temperature in humans is 36.8°C (98.2°F). Hypothermia can be divided in three stages of severity.
* Stage 1
Body temperature drops by 1-2°C (1.8-3.6°F) below normal temperature (35-37°C or 95-98.6°F). Mild to strong shivering occurs. The victim is unable to perform complex tasks with the hands; the hands become numb. Blood vessels in the outer extremities constrict, lessening heat loss to the outside air. Breathing becomes quick and shallow. Goose bumps form, raising body hair on end in an attempt to create an insulating layer of air around the body (which is of limited use in humans due to lack of sufficient hair, but useful in other species). Often, a person will experience a warm sensation, as if they have recovered, but they are in fact heading into Stage 2. Another test to see if the person is entering stage 2 is if they are unable to touch their thumb with their little finger; this is the first stage of muscles not working.
* Stage 2
Body temperature drops by 2-4°C (3.8-7.6°F). Shivering becomes more violent. Muscle mis-coordination becomes apparent. Movements are slow and labored, accompanied by a stumbling pace and mild confusion, although the victim may appear alert. Surface blood vessels contract further as the body focuses its remaining resources on keeping the vital organs warm. The victim becomes pale. Lips, ears, fingers and toes may become blue.
* Stage 3
Body temperature drops below approximately 32 °C (89.6 °F). Shivering usually stops. Difficulty speaking, sluggish thinking, and amnesia start to appear; inability to use hands and stumbling is also usually present. Cellular metabolic processes shut down. Below 30 °C (86.0 °F), the exposed skin becomes blue and puffy, muscle coordination becomes very poor, walking becomes almost impossible, and the victim exhibits incoherent/irrational behavior including terminal burrowing or even a stupor. Pulse and respiration rates decrease significantly, but fast heart rates (ventricular tachycardia, atrial fibrillation) can occur. Major organs fail. Clinical death occurs. Because of decreased cellular activity in stage 3 hypothermia, the body will actually take longer to undergo brain death.

but I will have to pleasure to join you again for the coming one: flights booked ! 
Now it's time for me to complete my stuff in order to be well prepared.
