A MILITARY BASE IN SOUTHEASTERN POLAND — On the front lines in Ukraine, a soldier was having trouble firing his 155 mm howitzer gun. So, he turned to a team of Americans on the other end of his phone line for help.
“What do I do?” he asked the U.S. military team member, far away at a base in southeastern Poland. “What are my options?”
Using phones and tablets to communicate in encrypted chatrooms, a rapidly growing group of U.S. and allied troops and contractors is providing real-time maintenance advice — usually speaking through interpreters — to Ukrainian troops on the battlefield.

Ukrainian soldiers prepare a U.S.-supplied M777 howitzer to fire at Russian positions Jan. 9 in Kherson region, Ukraine. A rapidly expanding group of U.S. and allied troops and contractors are using phones and tablets to communicate in encrypted chat rooms to provide real-time maintenance advice to Ukrainian troops on the battlefield.
In a quick response, the U.S. team member told the Ukrainian to remove the gun’s breech at the rear of the howitzer and manually prime the firing pin so the gun could fire. He did it, and it worked.
The exchange is part of an expanding U.S. military help line aimed at providing repair advice to Ukrainian forces in the heat of battle. As the U.S. and other allies send more and increasingly complex and high-tech weapons to Ukraine, demands are spiking. And since no U.S. or other NATO nations will send troops into the country to provide hands-on assistance — due to worries about being drawn into a direct conflict with Russia — they’ve turned to virtual chatrooms.
The U.S. soldier and other team members and leaders stationed at a base in Poland spoke recently to two reporters who were traveling with Army Gen. Mark Milley, chairman of the Joint Chiefs of Staff, when he visited the facility. Because of the sensitivity of the operation, the troops there spoke on condition of anonymity under guidelines set by the U.S. military. Reporters also agreed not to reveal the name or location of the base or take photos.

Analysis: Stakes rise as Iran can fuel ‘several’ atom bombs
AP file
For months, U.S. officials balked at sending M1 Abrams tanks to Ukraine, insisting they were too complicated and too hard to maintain and repair.
On Wednesday, that abruptly changed. Ukraine's desperate pleas for tanks were answered with a sweeping, trans-Atlantic yes.
The dramatic reversal was the culmination of intense international pressure and diplomatic arm-twisting that played out over the last week. And it resulted in in a quick succession of announcements: The U.S. said it will send 31 of the 70-ton Abrams battle tanks to Ukraine, and Germany announced it will send 14 Leopard 2 tanks and allow other countries to do the same.

Analysis: Stakes rise as Iran can fuel ‘several’ atom bombs

WHAT ARE THE ABRAMS?
M1 Abrams tanks have led American battle assaults for decades.
Carrying a crew of four, the Abrams was first deployed to war in 1991. It has thick armor, a 120 mm main gun, armor piercing capabilities, advanced targeting systems, thick tracked wheels and a 1,500-horsepower turbine engine with a top speed of about 42 miles per hour (68 kilometers per hour).
Crews interviewed in a 1992 Government Accountability Office review after the Persian Gulf War praised its high survivability and said “several M1A1 crews reported receiving direct frontal hits from Iraqi T-72s with minimal damage.”
More recently, the battle titans led the charge to Baghdad during America’s 2003 invasion of Iraq, as 3rd Infantry Division units conducted what was dubbed “Thunder Runs” to break through Iraqi defenses.
The Abrams' powerful jet engine can propel the tank through almost any terrain, whether heavy snow or heavy mud, said Kevin Butler, a former Army lieutenant who served as an Abrams tank platoon leader. Butler recalled a muddy exercise in the late 1990s at Fort Stewart, Georgia, where he’d voiced concern about the tanks getting stuck because it had already stuck the Humvees.
The Abrams, he said, "didn’t even notice” the mud.

WHY THE U.S. KEPT SAYING NO
The Abrams' jet engine needs hundreds of gallons of fuel to operate.
It will burn through fuel at a rate of at least two gallons per mile (4.7 liters per kilometer), whether the tank is moving or idling, Butler said, which means a constant supply convoy of fuel trucks must stay within reach so it can keep moving forward.
The U.S. worried that the fuel demands would create a logistical nightmare for Ukrainian forces. While an Abrams can storm through the snow and mud, fuel trucks can't. In addition, like any jet engine, the Abrams' turbine needs air to breathe, which it sucks in through filtered rear vents. When those vent filters get clogged — whether by sand, as soldiers reported to GAO in 1992, or by debris they might encounter in Ukraine — they can't perform.
“The Abrams tank is a very complicated piece of equipment. It’s expensive, it’s hard to train on. ... It is not the easiest system to maintain. It may or may not be the right system,” The under secretary of defense for policy, Colin Kahl, told reporters last week at the Pentagon.
The Abrams also will require months of training. Ukrainian forces will have to learn how to operate its more complex systems, and how to keep it running and fueled.

THE ARM-TWISTING TURNABOUT
Despite all the drawbacks expressed by the U.S., when all was said and done, it came down to political realities and a diplomatic dance.
Germany had been reluctant to send the Leopards, or allow allies to send them, unless the U.S. put its Abrams on the table, due to concerns that supplying the tanks would incur Russia’s wrath. The U.S., meanwhile, argued that the German-made Leopards were a better fit because Ukrainian troops could get them and get trained on them far more quickly and easily.
The impasse frustrated European allies, such as Poland, who wanted to send Leopards but couldn’t without Germany’s OK. Thus began the more fierce negotiations.
U.S. and German officials both used the word “intensive” to describe the talks that ultimately led to the tank turnabout by both countries.
“This is the result of intensive consultations, once again, with our allies and international partners,” Chancellor Olaf Scholz, pictured, said in an address to German lawmakers on Wednesday.
Echoing Scholz, a senior U.S. administration official said talks had been going on for some time but “in a much more intensified way over the last number of weeks.” The official spoke on condition of anonymity to provide details on the decision.
From President Joe Biden on down, calls were made, including to Scholz. Defense Secretary Lloyd Austin and Army Gen. Mark Milley, chairman of the Joint Chiefs of Staff, spoke and met with their German counterparts and other allies.
Last Friday, the pressure was palpable. Top defense leaders from more than 50 countries met at Ramstein Air Base in Germany to discuss Ukraine's ongoing weapons and equipment needs. Tanks were a key subject. Leaders from countries that have Leopard tanks met with the new German defense minister.
Gradually, the German stance began to publicly soften, leading to Wednesday's announcements. Asked repeatedly what changed, Biden administration officials sidestepped. Asked directly about German pressure, Biden told reporters, “Germany didn’t force me to change our mind.”

HOW LONG WILL IT TAKE?
Timing for both delivery of the tanks to Ukraine and the training of Ukrainian troops is fuzzy. U.S. officials would only say that it will take “many months” to deliver the Abrams tanks, but that the Leopards will arrive faster.
Doug Bush, assistant secretary of the Army for acquisition, said the U.S. no longer buys new Abrams, but uses older ones as “seed vehicles” and refurbishes them. Doing that, however, isn't quick or easy, he said.
The training can begin more quickly, and the Pentagon is developing a program.
“We want to make sure that they (the tanks) fall on ready hands, and that the Ukrainians know how to use them, they know how to keep them running, and they’ve got the supply chain in place for spare parts and supplies," said National Security Council spokesman John Kirby.
Bush said the Ukrainians have shown they have the knowledge and capabilities to learn new systems quickly.
“We can often abbreviate and accelerate what we can do in terms of training for Ukrainian army soldiers,” he told reporters Wednesday. "With enough motivation and dedicated 24/7 access to them, we can train people really quickly,” he said. "The U.S. Army knows how to do that.”

Fixing a howitzer, the repair team said, has been a frequent request from Ukrainian troops on the front lines. The need for help with weapons as been growing. Just a few months ago, there were just a bit more than 50 members of what they call the remote maintenance team. That will surge to 150 in the coming weeks, and the number of encrypted chat lines has more than tripled — from about 11 last fall to 38 now.
The team includes about 20 soldiers now, supplemented by civilians and contractors, but the military number may dip a bit, as more civilians come on board. And they expect it will continue to evolve as new sophisticated weapons are delivered to the Ukrainians, and new chatrooms set up to handle them.
“A lot of the times we’ll get calls from right there on the firing line, so there’ll be outgoing or incoming fire at the same time you’re trying to help the forward maintainers troubleshoot the best they can,” said a U.S. soldier who is part of the maintenance team. Sometimes, he said, the chat has to wait a bit until troops can get to a safer location.
A key problem, said one officer, is that Ukrainian troops are pushing the weapons to their limits — firing them at unprecedented rates and using them long after a U.S. service member would turn them in to be repaired or retired.
Holding up his tablet, the U.S. soldier showed photos of the barrel of a howitzer, its interior ridges nearly worn completely away.
“They’re using these systems in ways that we didn’t necessarily anticipate,” said the officer, pointing to the tablet. “We’re actually learning from them by seeing how much abuse these weapon systems can take, and where’s the breaking point.”
The Ukrainian troops are often reluctant to send the weapons back out of the country for repairs. They’d rather do it themselves, and in nearly all cases — U.S. officials estimated 99% of the time — the Ukrainians do the repair and continue on.
Many of the chats are regularly scheduled with depot workers in Ukraine — like the one they call “Coffee Cup Guy,” because his chat has a coffee cup emoji. Other times they involve troops on the battlefield whose gun just blew apart, or whose vehicle stalled.
Sometimes video chats aren’t possible.

“A lot of times if they’re on the front line, they won’t do a video because sometimes (cell service) is a little spotty,” said a U.S. maintainer. “They’ll take pictures and send it to us through the chats and we sit there and diagnose it.”
There were times, he said, when they’ll get a picture of a broken howitzer, and the Ukrainian will say, “This Triple 7 just blew up — what do we do?”
And, in what he said was a remarkable new skill, the Ukrainians can now put the split weapon back together. “They couldn’t do titanium welding before, they can do it now,” said the U.S. soldier, adding that “something that was two days ago blown up is now back in play.”
Doling out advice over the chats means the U.S. experts have to diagnose the problem when something goes wrong, figure out how to fix it, then translate the steps into Ukrainian.
As they look to the future, they are planning to get some commercial, off-the-shelf translation goggles. That way, when they talk to each other they can skip the interpreters and just see the translation as they speak, making conversations easier and faster.
They also are hoping to build their diagnostic capabilities as the weapons systems get more complex, and expand the types and amount of spare parts they keep on hand. For example, they said the Patriot missile system the U.S. is sending to Ukraine will be a challenge, requiring more expertise in diagnosing and repairing problems.
The team in Poland is part of an ever expanding logistical network that stretches across Europe. As more nations send their own versions of weapon systems, they are setting up teams to provide repair support in a variety of locations.
