BGM-71 is one of the three starter Heavy Ordnance Corps (HOC) units available to the Commander. Her most important stat is Pierce and she prioritizes enemies with the most Shielding.

An achievement for performing Data Analysis once with Original Samples will immediately grant the player 5 copies of BGM-71, unlocking her for usage. 

The extremely high Pierce stat of BGM-71 makes her ideal for breaking enemy Force Shields. Since Pierce value is also used to determine damage dealt by player HOCs to enemy structures, BGM-71 also performs well at demolishing enemy structures, so long as her lower range of 2 tiles isn't an issue. 

Because BGM-71 excels at two of the three main niches HOC units fill, she is the highest priority HOC to Skill Train and level.

Initial Stats → Level 100 → Theoretical Max*

*Includes maximum Iteration and Chip bonuses

Lethality 52 → 155 → 548 Pierce 135 → 402 → 892
Precision 118 → 349 → 647 Reload 28 → 83 → 154

Minimum Enhancement Capsules to max: x297

  • Lethality: 155 - 52 = x103
  • Pierce: (402 - 135) / 3 = x89
  • Precision: (349 - 118) / 3 = x77
  • Reload: (83 - 28) / 2 = x28


Charged Missile
Level 10 Effect Fires an enhanced missile after every 2 normal attacks to deal an extra 1.8x Lethality to the center and increase this unit's Pierce by 60% for 8 seconds. The first attack is always an enhanced missile.

(1st, 4th, 7th... shots are enhanced missiles.)
Reload Procedure
Level 10 Effect Increase Reload Speed by 8% after every reload. Max 5 stacks.
Thrill of the Hunt
Level 10 Effect Increase Lethality by 10% per hit on the same target. Max 5 stacks.

Full Analysis

BGM-71 is the strongest HOC for hard countering enemy Force Shields, and should be raised to level 40 then 60 (as soon as the player finishes upgrading the Training Range to Level 10) so that BGM-71 can equip 5★ Chips to raise her most important stat, Pierce.

  • This requires x209 and x836 respectively. The Black Market sells x600 each month, so there should be plenty to let her reach Level 60 before Continuum Turbulence
  • While BGM-71 ought to be raised as a priority over 2B14 and AGS-30, the other two HOCs should still be leveled when the player has resources to spare. 

Her normal attack deals 1.5x Lethality and 1x Pierce to the main target, as well as 0.5x Lethality and 1x Pierce to enemies within a 1.5 radius AoE.

Since BGM-71's first shot is always a Charged Missile that deals up to 1.8x Lethality and she prioritizes the most shielded target, this can instantly neutralize force shields on the most threatening enemies and makes BGM-71 invaluable for fights against enemy factions that frequently deploy shielded enemies. 

Skill Training Priority
Charged Missile
Lv. 10 ASAP
This is BGM-71's most important Skill for her role of breaking Force Shields, and should be maxed ASAP.

With sufficiently high Reload Speed, this can last for multiple shots. Raising her Reload Speed to 151 (maxed 5★ Circuit Board plus Level 8 Iteration) allows it to last for three shots, making the buff essentially permanent.
Reload Procedure
Lv. 1 > 4 > 7 > 10
Reloading Procedure is helpful, but the gain of 5% to 8% per stack from Lv. 1 to Lv. 10 makes it a lower priority than Charged Missile.

It can be leveled as a late-game minmax.
Thrill of the Hunt
Lv. 1 > 4 > 6 > 10
Thrill of the Hunt may seem to add a decent amount of damage, but BGM-71 doesn't fire all that often at low rarity so it's unlikely this would stack up to make a difference in most encounters.

This should be leveled later once BGM-71 is at a higher rarity and can fire decently quickly.

Players should prioritize Chips with high Pierce when equipping BGM-71.

  • Reaching the stat cap for Pierce is much more important than the same color bonus - don't be afraid to use off-color chips to achieve that. 

After Pierce is maxed, investing in Reload can help BGM-71 land subsequent hits faster in fights with multiple shielded enemies. 

Lethality and Precision are less important (especially since the Pierce force shield damage cannot miss) but can be increased if the player is able to do so with minimal opportunity cost.

Swap out pieces for the Same Color Bonus only when it results in a net increase of stats. 

Since the player will be rearranging the Circuit Board each time BGM-71 increases in rarity, it's not necessary to rotate (calibrate) Chips until she reaches 5★ rarity. It is nevertheless relatively safe to enhance Chips (even low rarity chips) so long as the enhancement fodder is of the same color, since you can simply feed your enhanced chips to better chips and have most of the stored EXP (80% of its accumulated EXP) carry over. 


The BGM-71 TOW ("Tube-launched, Optically tracked, Wire-guided") is an American-made anti-tank missile first produced in the 70s. It's seen use in numerous wars across the world and is widely fielded even today. 

  • BGM-71 is the only HOC unit with four operators, but only three of them (excluding the operator with blonde hair) have a dorm idle animation.
  • Each operator's costume has motifs corresponds to playing card suits. 
    • From left to right: Spades, Diamonds, Hearts, and Clubs.
  • In BGM-71's defeat animation, Clubs is seen chasing after Hearts, who panics and runs the wrong way towards the enemy. 
  • The exact same Skill icon is used in-game for both Reload Procedure and Thrill of the Hunt. For differentiation purposes, this article has replaced the icon for Reload Procedure
