It was 30 years ago for me. We called them "Jump drills" the crew needed to be at the airfield in two hours with full kit.
Line spacing sounds about the same, between 10-20 ft. spacing depending on terrain and situation.
It's the fire camp, not the line, that has me worried. I've been in camps with 1500 fire-fighters, and another 1000 prisoners doing mop-up, in hideous unsanitary conditions.
In any case, thank you for what you do, and stay safe as well.
for tree planting, not a Pulaski.
A Pulaski is a fire tool with a pick on one side and a axe blade on the other.
A hoedad is like a very long bladed hoe (they come in different sizes) that is hit into the ground and rocked to make a hole for planting bare root or container seedlings.

Pulaski
On August 20, 1910, Pulaski was credited with saving all but five of his 45-man crew during what is known as the "Great Idaho Fire," the "Great Fire of 1910" or the "Big Blowup." It had been unusually dry in 1910 and forest fires were rampant across the northern Rockies. Pulaski was supervising crews on the west fork of Placer Creek, about five miles south of Wallace when the fire suddenly broke out of control, overwhelming the crew.
Drawing on his knowledge of the area and of the dynamics of forest fires, Pulaski led his men to safety in an abandoned prospector's mine. After ordering his crew into the mine tunnel, he threatened to shoot with his pistol any man who left. Lying prone on the tunnel floor, all but five of the firefighters survived, though Pulaski himself was temporarily blinded by the fire and smoke. The two horses with them died from smoke inhalation. The mine entrance, now known as the Pulaski Tunnel, is listed on the National Register of Historic Places.
Pulaski remained with the Forest Service until 1929, though the great fire's smoke and flames had damaged his lungs and eyes; during that time he petitioned the government for money to care for the graves of the dozens of firefighters killed by the 1910 fire, and for compensation for his wounds.
The photo above and below shows the Nicholson Mine entrance that US Forest Service Ranger Ed Pulaski used to shelter and save 40 out of 45 of his group of firefighters battling the Great Idaho Fire of 1910. That fire led to the expansion of the US Forest Service, and many other major changes in the way forest and wildland fires were fought in America.
Many states are treating it like it is over already.
I had to get out and about today and the amount of "unprotected" person was unbelievable...except that I live in a RED RED part of the country sooooooooooooooooooo, I suppose it was completely expected.
My late father was career USFS. In retirement, he drove busses full of fire crews between camps and helicopter communication trailers from hot spot to hot spot...he loved the wild land firefighting community so much. It was in his blood. Thanks for what you do and welcome to DU! 
that maybe your dad and me crossed paths doing something we believed in. After we landed in Helena, were on multiple buses. The drivers were a little crazy, but everyone wanted to get there YESTERDAY!
Those were proud days, I'm also glad I'm too old to do them again.
And when it was done, a hot shower, a home-cooked meal, a cold beer , and clean sheets sounded like the most priceless gifts in the universe. (sex wasn't even in the top 5...well...maybe #5) 
I also served in the military, but not in combat, so this might be my only "band of brothers" moment. Thanks for helping me remember.
