The MGPTS tent is a pole supported modular structure. The MGPTS tent is issued in four sizes: small, command
post, medium and large. The MGPTS can also be complexed in various combinations of length and to other types of
equipment.
SITE REQUIREMENTS
NOTE
These instructions are based on the medium MGPTS. For other tent sizes, the number of mid sections
and poles will differ. Make modifications as required.
Select an area to erect the tent. Ensure the area will be large enough for the tent and guy ropes that will be erected
(see Table 1). The area should be clear of trees, rocks and debris. Choose a relatively flat area; the ground should
not vary by more than 6 inches. A trench should be dug around the perimeter of the tent about 2 feet away from the
edge. A drainage ditch should also be dug for water to exit the perimeter trench.
Table 1. Area Setup Requirements.
Tent Model: Length Width Height
Small 34 ft 34 ft 12 ft
Command post 43 ft 34 ft 12 ft
Medium 52 ft 34 ft 12 ft
Large 70 ft 34 ft 12 ft
ASSEMBLY TENT SYSTEM
Layout fabric sections
1. Identify each fabric section required. For the medium MGPTS, you will need two end sections and one mid
section.
WARNING
Fabric sections are heavy. Always lift with your legs not your back. Failure to observe this warning
may result in back injury.
2. Transport each required fabric section into area where tent will be erected.
3. Unfold each mid section (1) and end section (2) so that the inside (white side) is down and the green or tan side
is up. Place these sections in center area where tent is to be setup.
NOTE
The mid section (1) has lace and grommets on both ends. The end sections (2) have lace and
grommets on one end.

2
4. Position end sections (2) on either side of the mid section (1) so that becket laces (3) align. Lay tent out flat.
Fold side walls and end walls of mid (1) and end sections (2) under roof section so that only roof portions are
exposed. This will allow easier access to the web loop attachment points.
Connect fabric sections
Use the following procedures to connect becket lace between each end section and mid section:
NOTE
Split the four personnel into two person teams. Each team should perform steps 1-11 at the same time
on opposite ends of the tent.

3
1. Find the two large snap hooks (1) at the center edge of end section and mid section roofs on underside of tent.
Connect the snap hooks (1).
2. Find becket lace (2) at one end of roof. You may start at either end of roof.

4
3. Lace the fabric sections together by using the following instructions. Insert the first rope loop (1) on one roof
section through the first small grommet (2) of the adjoining roof section (3). Loops always enter the white
side of the fabric and exit the green or tan side. All loops should be pulled tight. Insert the second loop (4)
through the second grommet (5) and through the first loop (1). Insert the third loop (6) through the third
grommet (7) and the second loop (4). Repeat this pattern until reaching the other side of the tent.
4. At the end, tie off last becket lace by using the following instructions: Insert the next-to-last becket lace (8)
through loop of last becket lace (9). Pull the next-to-last becket lace (8) back towards the ridge and tie off with
half-hitch knot.
5. Pull 1-1/2 inch web pole loop (10) through big grommet (11) at perimeter.

5
6. Connect d-ring (12) on 3/4 inch strap at the eave to adjoining section’s snap hook (13).
NOTE
Make sure d-ring strap is below 1-1/2 inch web pole loop.
7. Fold one flap (14) over becket lace.
NOTE
Flaps are identical. It does not matter which is on top or bottom.

6
8. Feed 1-1/2 inch web pole loop (10) at eave through slit in flap (14).
9. Fold other flap (15) along the length of the tent over the first flap (14) and feed 1-1/2 inch web pole loop (10)
through slit in outer flap (15).
10. Connect buckles (16) along entire outer flap (15).
11. With one person at each corner of the tent, stretch fabric tight to remove slack.
Setting up tent poles
NOTE
Stay in your two person teams to perform the following procedures.
NOTE
Side poles are not adjustable. For the medium MGPTS ten side poles will be used.
1. Locate side poles (1).
2. Make sure each side pole (1) has two guy ropes (2) attached to cap assembly (3).
3. Place one side pole (1) at each corner of tent (4), and at each 1-1/2 inch web loop along the side eave. Place
cap assembly spindle (5) through 1-1/2 inch web loop (6) at eave.

7
NOTE
At each corner of the tent make sure web loops are pulled through slit in fabric shingle.
4. Find two end poles (1). Adjust them to maximum height by pulling pin (2) out at bottom of pole. Push pin (2)
back in when holes are aligned. Place cap assembly spindle (3) through 1-1/2 inch web loop at middle of each
tent end section’s roof edge. Ensure the flat side of the pole is on the ground with the pin facing up, so that guy
ropes slide freely through ring at top.

8
5. Corner poles should be aligned with fabric seam (1) in end section roof. Stakes may then be placed 6 feet out
along pole and 1-foot on either side of pole.
6. Follow staking diagram below. Drive in the 36-inch wood stakes at all points indicated on diagram. It is
important to have a stake at each of the marked points.
NOTE
For the stakes located on the sides of the tent, a corner pole may be used to properly locate the stakes
by the following procedure: A pair of stakes will be located for each web loop located on the sides of
the tent, place a corner pole at each web loop (facing away from tent) then place a stake 1 foot on each
side and 1 foot from end of corner pole (6 feet from the web loop). Repeat this procedure for each
stake pair on the side of the tent, after you have finished, return the corner pole to where it was
originally placed (aligned with fabric seam).

9
7. Drive stakes six feet out from tent edge and angle stake slightly away from tent. Wood stakes should be driven
in until only six inches extend above the ground.
8. Place corner pole guy ropes (1) over wood stakes (2), making sure that ropes are not twisted or crossed.
Loosen rope adjustment to leave plenty of slack. This will make it easier to stand poles up. Repeat for all
corner pole locations.
9. Start at one corner. One person lifts corner roof fabric (3) while the second person grasps pole (4) and rotates
bottom of pole under roof fabric (3) and stands pole up so that bottom of pole is angled in toward center of
tent. Tighten guy ropes (1), by sliding tensioner (5), to keep poles from falling.
10. Repeat step nine for other two corners.
NOTE
Guy ropes must be snug, to keep poles from falling.
11. Stand side poles up along each side of the tent. One person lifts roof fabric (3). Other person grasps pole (4),
rotates bottom of pole under roof fabric (3) and stands pole up so that bottom of pole is angled slightly in
towards center of tent. Tighten guy ropes (1) to keep poles from falling.

10
12. Repeat step eleven for all side poles.
13. Two persons are required. Stand end pole up. One person lifts roof fabric (3). Other person grasps pole,
rotates bottom of pole under roof fabric (3) and stands pole up so that bottom of pole is angled slightly in
towards center of tent. Place flat side of end pole towards tent so that guy ropes slide freely through ring at
top. Tighten guy ropes (1) to keep pole from falling. Repeat for other end pole.
WARNING
Use care to ensure fingers, or other parts are not caught in y pole hinge point.
Raising the tent
1. Roll up one 9-foot long sidewall of tent. Use tie straps at eave to secure the rolled up section.

11
2. Locate y poles (1). Identify the peak fittings (2) which are metal tubes attached to flat metal plates located
on the inside of the roof fabric. Using two people carry each y pole (1) into tent through the sidewall
opening. Do not open y-arms while carrying y pole. Position y poles (1) on ground. Unfold y-arms. Tops
of y-arms should be located under peak fittings (2) on bottom side of tent.
3. Raise y pole. With one person holding each y-arm (3) and the third person grasping the pole body, place
peak fittings (2) all the way into ends of the y-arms (3).

12
WARNING
Use care to ensure fingers, or other parts are not pinched while inserting y-arms into peak fittings.
4. Once both peak fittings (2) are inserted into y-arms (3), lift y pole (1) to a vertical position.
5. Repeat this procedure for all y poles.
6. From one end, view y poles and make sure they are aligned.
Tensioning tent system
1. Tensioning tent. Corners should be tensioned first. Tension one corner at a time.
a. Start at a corner. The first person should position himself between the stakes (1) and pole (2). The same
person should grasp pole (2) at the top and below cap assembly with both hands. This person rocks back
towards stake (1) keeping base of the pole in place. Second person slides down tensioner (3) to tighten
guy ropes (4). Both people grasp pole and straighten pole (2) to a vertical position.
b. Repeat procedure on other three corners.
c. Repeat this procedure on side poles.
d. Repeat this procedure for the two end poles until entire tent is tensioned.

13
NOTE
Sidewall can be configured in three different ways: all walls down, cloth walls rolled up with screen
walls down or both cloth walls and screen walls rolled up.
2. Secure vertical fabric sections. Pull wind tie straps at all side pole locations through slit in opposing wall
section. Tie all wind straps at side pole and end pole locations securely to the poles. Starting at the top, attach
vertical fabric sections together with hook and pile fasteners and buckles on flaps.
3. Attach hook and pile fasteners on rain flaps to sidewall flap for blackout integrity.
4. Staking sidewalls and poles:
a. Locate the 12-inch polycarbonate stakes.
b. Locate the rope loops (1) facing out at the base of the Side Walls.
c. Insert finger into a rope loop (1), twist rope loop to form a figure 8. Place the two newly created loops
around finger. Insert stake into both loops and drive stake into ground.

14
NOTE
Do not drive 12-inch stakes all the way into the ground, leave them about two inches out, this will
make it easier to remove the stakes.
d. Repeat step c for all rope loops.
e. Drive a stake through the stake tube (2) at base of poles.
f. Repeat this procedure for all stake tubes.

OPERATING PROCEDURES
Operate doors
Use following procedures to operate the doors on the MGPTS:
Door is opened and closed using hook and pile fasteners. The inner door can be rolled up (towards the inside to
prevent rain from being trapped within the folds) and secured with straps at the top.
Outside the tent there is a sliding door. The sliding door can be secured in the open position with attached straps,
and secured in the closed position with buckles.
Operate windows
Windows can be opened for ventilation or closed due to inclement weather. Windows have three panels.
The fabric cover and clear windows are closed by hook and pile fasteners.
The fabric cover and clear window can each be held open with tie tapes.
Each layer must be rolled up towards the inside to prevent rain from being trapped within the folds.
To fully close the fabric cover, the clear window must first be unrolled and secured.
Operate roof vents
WARNING
Do not use any type of non-vented heaters. The use of non-vented heaters will cause the accumulation
of carbon monoxide gas. Carbon monoxide gas is not visible and it has no smell. If symptoms such as
headache, dizziness, fatigue, nausea, or irregular breathing occur, move affected personnel to fresh air.
Failure to comply with this warning may result in personal injury or death.
All fuel burning heaters consume oxygen. Adequate ventilation must be maintained at all times. Keep
roof vents clear of snow, ice, or debris. Open doors, windows, flaps, hook and pile fastener wall
closures as needed to introduce sufficient fresh air to replace oxygen consumed by heaters. If
symptoms such as headache, dizziness, fatigue, nausea, or irregular breathing occur, move affected
personnel to fresh air. Failure to comply with this warning may result in serious injury or death to
personnel.
NOTE
Roof vent is made from foam and is always open, no operation is required.
